Re: [R] How to identify runs or clusters of events in time
Mark, I did something similar a couple of year ago by coding non-events as 0, positive events as +1 and negative events as -1 then summing the value through time. In my case the patterns showed up quite clearly and I used other criteria to define the actual periods.

You want to identify periods when the event occurs more frequently than the base rate of occurrence. Ideally, you don't want to have to specify the period (e.g., break into months), so the analysis can be sensitive to scenarios such as many events happening only between, e.g., June 10 and June 15 - even though the overall number of events for the month may not be much greater than usual. Similarly, there may be a cluster of events that occur from March 28 to April 3. Ideally, you want to pull out the base rate of occurrence and highlight only the periods when the frequency is less or greater than the base rate. 2) Events again occur repeatedly over time in an inconsistent way. However, this time, the event has positive or negative outcomes - such as a spot check of conformity to regulations. You again want to know whether there is a group of negative outcomes close together in time. This analysis should take into account the negative outcomes as well though. E.g., if from June 10 to June 15 you get 5 negative outcomes and no positive outcomes it should be flagged. On the other hand, if from June 10 to June 15 you get 5 negative outcomes interspersed between many positive outcomes it should be ignored. I'm guessing that there is some statistical approach designed to look at these types of issues. What is it called? What package in R implements it? I basically just need to know where to start.

Hmm... I once learned
'()' =: parenthesis/es
'[]' =: bracket(s)
'{}' =: brace(s)
Of course, I'm not a native English speaker, and my teacher(s) /
teaching material may have been biased ... but, as all three
symbol pairs play an important role in R, I think it would be
really really helpful, if we could agree on using the same
precise English here.
I'm happy to re-learn, but I'd really like to end up with three
different simple English words, if possible.
(Yes, I know and have seen/heard "curly braces", "round
parentheses", ... but I'd hope we can do without the extra adjective.)
Thank you, well versed English (or "American") learned readers
of R-help, for wise guidance on this ...

Bill,
Your final words, "changes in spring and fall" reminds me of a problem
I have yet to solve. Most of my data is logged in standard time (no
daylight times) but often I see the note "daylight time encountered
switching to UTC" even when I've specified "tz="PST".
I hope I've been missing something simple--any suggestions?

I use difftime(x, y, units=) instead of the similar x-y because the latter
chooses
the units based on how far apart x and y are, while the former gives me
consistent
units:

Depending on what you are using this for, you might want to compute time
since 3am
of the current day so you don't get discontinuities for most times when the
time
changes in spring and fall.

(independent of a date), unless I have missed something. What is the best
way to create a time variable so that I can aggregate and plot by time of

all date/times to the same date. I can then manage the rest of what I want

Here is a sample data frame.

Re: [R] Visualization of people's interactions by participation to parties
Hendrik, As a start, I'd make a matrix of zeros with the parties in rows and all of the participants as columns and put a one for each participant at each party. The matrix will consist of a vector for each participant showing the parties attended. The pattern may suggest the next step. Similarity of vectors could be an indication of interaction.

Using a screen reader like Window-Eyes, the student could use the R GUI environment, although it’s a little frustrating because it doesn’t speak a lot and you need to use the mouse keys a lot. The other option if you have to stick with Windows is to run R at the command prompt, which makes interaction slightly easier but you’d have to figure out how to log the output.

I would like information from R developers/users about how/how well R interfaces with Excel (an easier skill set to find!) In your opinion, could it be as easy as uploading data from excel into R? Also, do you know of a way to enlarge the R interface or otherwise assist in making the program accessible to a low vision person? My limited understanding leads me to believe that screen magnifiers like zoom text don't work particularly well. If you have information on that, I would very much appreciate it. Thanks for your help and for bearing with me! Courtney I am a bit confused (a normal condition for me). Is the student writing R code or is the student running a application written in R? Also, since you mentioned Excel, I am assuming that the student is using a PC running Windows as opposed to Linux or a Mac. If the student is writing R code, then I'd suggest that your computer support person install Rstudio. It is cost free and can be downloaded here: http://www.rstudio.com/ . The installer can then customize Rstudio to use a really large font, if that would be helpful. Please forgive my lack of knowledge about accessibility issues. If the student has trouble typing (mobility issue?), this likely won't help. Would a speech to text / text to speech interface help instead of a screen magnifier? I know next to nothing about these tools, other than that they exist. === If the student is running an R application (which is what enter data for her implies to me), then any accessibility issues would need to be addressed in the application itself. But I don't understand why a data entry assistant would need any skills in R itself in order to enter data into it. But without knowing more, that's about all that I can say. One thought: CMU has a college teaching electrical and computer engineering. Depending on what that means, perhaps someone from that college (professor, TA, or grad student) could see what your student is doing and perhaps have some insights on how to help. Or is there a computer club on campus where some geeky student might be found? You might look here: http://www.club.cc.cmu.edu/ If these are true geeks (and the web site sounds promising), then a lure of beer pizza would likely be irresistible grin. === For interfacing R with Excel, you might want to look at RExcel here: http://rcom.univie.ac.at/download.html#RExcel . It has a free student version. But is this more for an Excel user who wants to use R for analysis, not an R user wanting to use Excel for data entry. -- Yoda of Borg, we are.

md[2,3] - NA
md[4,1] - NA
md
I want to count number of 5s in each column - by device. I can do it like
this:
library(dplyr)
group_by(md, device) %%
summarise(counts.a = sum(a==5, na.rm = T),
counts.b = sum(b==5, na.rm = T),
counts.c = sum(c==5, na.rm = T))
However, in real life I'll have tons of variables (the length of
'myvars' can be very large) - so that I can't specify those counts.a,
counts.b, etc. manually - dozens of times.
Does dplyr allow to run the count of 5s on all 'myvars' columns at once?

Here's an example, the script 'pairwise-plots-continuous-vars.R' consists
of this function:
plotpairs - function(x1,x2,x3,y,plotmain) {
require(compositions)
opar - par(mar=c(4,4,3,1))
NO3 - x1
SO4 - x2
pH - x3
pairwisePlot(cbind(NO3,SO4,pH),clr(y),add.line=T)
title(main=plotmain)
par(opar)
detach('package:compositions')
return()
}
(I suppose the return statement is superfluous since there is no value
returned to a calling function.)
What I want to do is call plotpairs() with appropriate arguments for each
plot as needed.
TIA,

Intel Xeon E5-2640 v3 - 8 cores 2.6 GHz Turbo I don't know what is better in simulations studies in R, a few very fast cores or many cores at normal speed. It's **very** hard to answer such general questions reliably, but I'll take a guess and say that if you're doing simulation studies you're likely to be doing tasks that are easily distributable (e.g. many random realizations of the same simulation and/or realizations for many different sets of parameter values) and so the more-cores option will be a good idea. But it's possible that what you mean by simulation studies is different. If you can do some benchmarking of your problems on an existing machine that would probably be a good idea. Unfortunately unless it is of very similar architecture that may not help much. Three issues hard to scale from are the 'Turbo', the hyperthreading of modern Xeons and the cache sizes. Now, I happen to have machines with multiple E5-24x0 and E5-26x0 Xeons: both do hyperthreading well, so you would have 8 or 16 virtual CPUs and they will give you say 50% increase in throughput if all the virtual cores are used. But you cannot scale up from using just one process on one core. I find it hard to think of tasks where option 1) would have more throughput, but if most of the time you are not running things in parallel then the higher speed on a single task is a consideration.

I justify the names of these 2 functions using the same logic that suggests short and simple names for functions that you would expect to be used often. even the tortuous way to always return a p-value == 0: It turns out (discovered by accident and then brought to my attention) that if you run SnowsPenultimateNormalityTest on a vector of length 0 then it does return a p-value of 1. I have not yet decided if this is a bug or a feature. On one hand it makes sense that a sample of size 0 is perfectly consistent with the assumption that you chose 0 observations from a normal distribution, on the other hand, if it is an integer or double vector of length 0 that would still be information that the numbers (or lack thereof) are rational. [snip] I am just curious... Are there teachers out there pointing to that test? If yes, what fraction of the students realise what happens? I guess, it is closer to zero than to one, unfortunately. Wait... I need another SnowsPenultimateXxxxTest() here to check the null hypothesis that all my students are doing what they are supposed to do when discovering a new statistical tool! I don't know of any teachers pointing to the test, I would want to be careful which class to bring it up in. For some students it could result in an epiphany, others may just blindly use it, and still others may have their heads explode if they have to think to hard about it. I was originally considering naming the test SnowsAntepenultimeateTest to give a little more room for follow-up tests, but at the time I could not remember if it was Ante (before) or Anti (opposite). I learned the word Antepenultimate in terms of pages in a book, where the 3rd to last page (the Antepenultimate page) is directly opposite (Anti-) the Penultimate page. Just in case that is not confusing enough, the ultimate page of a cheap detective novel is the last page where the hero realizes that since the motive for the murder was to cover up the murderer's embezzlement of the family fortune to pay off his bookie, the hero will not be paid after all and will still need to continue avoiding his loan shark. The penultimate page is the second to last page where in response to the hero's listing of circumstantial evidence the murderer conveniently confesses and fills in all the missing details saving the embarrassment to the hero if he had just lawyer-ed up and been acquitted due to lack of hard evidence. And the antepenultimate page is the 3rd to last where the hero utters the cliche phrase You are probably wondering why I gathered you all here. I don't know what the 4th to last page would be called (could add another ante-, or in R just use tail(book,4)). -- Gregory (Greg) L.

I would generally agree with you, except for a few points. 1. I avoid StackOverflow, because they claim copyright on the compilation. As I read their terms of service, it would be illegal for anyone to download and duplicate all postings about R. So a posting there is only available as long as they choose to make it available. Postings to the mailing list are archived in several places. It seems that StackOverflow is officially proposing user-generated content for download/mirroring: http://blog.stackoverflow.com/2014/01/stack-exchange-cc-data-now-hosted-by -the-internet-archive/?cb=1 All community-contributed content on Stack Exchange is licensed under the Creative Commons BY-SA 3.0 license. And it is currently being mirrored at least at the Internet Archive: https://archive.org/details/stackexchange So, in principle, it would be possible/desirable to: - spin the 'r' tag from StackOverflow and propose an r.stackexchange.com at http://area51.stackexchange.com/categories/8/technology . Such a SE site would be similar to http://mathematica.stackexchange.com/ - involve R Core to give blessing for using the R logo, if necessary. This would be similar to what Ubuntu does with AskUbuntu: http://meta.askubuntu.com/questions/5444/is-ask-ubuntu-official-ubuntu - set a mirror on r-project.org for all the user content that is produced by r.stackexchange.com , and thus allow R Core to keep the info publicly available at all times.

Well, I've seen my fair share of advertisements on Gmail, Yahoo Mail or what have you. I know some use dedicated clients, but not all do. (And sofar I haven't noticed one single intrusive or distracting ad on SE.) As for the number of votes, this is actually the most useful bit of this QA interface: it allows for the best questions (or most often asked) to stand out from all the noise. And it allows for the best answers (or those most authoritative) to stand out, too. Accepted answers immediately indicate to others seeking similar help what has worked for the OP. Very useful stuff. Voting also naturally allows to differentiate between neophytes (100), and professional helpers (1k; think of Brian, David or, as it happens, Bert). If you remember long ago someone proposed on r-help a reputation system for our professional helpers, only to be rebuffed essentially because it is unfeasible in a ML interface. The SE QA web interface---or similar---naturally handles this. - In most if not all cases, one has to login before posting. I have too many usernames and passwords as it is. Fair point. However SE found a neat way around this: it keeps cookies around and whenever you close the browser and reopen SE, it identifies the cookie and auto-logs you in.

Re: [R] time series has no or less than 2 periods
Perhaps looking at your data will suggest an appropriate number, viz. plot(data,type=b,xlim=c(0,20),ylim=c(0,50)) par(new=T) ind-1:19 # in this case where the data length is 19 data.ind-data.frame(ind,data) data.lo-loess(data~ind,data.ind) data.pre-predict(data.lo,data.frame(ind = seq(1,19,1))) plot(data.pre,pch=3,col=2,xlim=c(0,20),ylim=c(0,50)) If you now plot the difference between the data and the loess prediction, data.ind-cbind(data.ind,data.pre) data.diff-with(data.ind,data-data.pre) data.ind-cbind(data.ind,data.diff) with(data.ind,plot(ind,data.diff,type=b)) abline(h=0) there is also a pretty strong two week signal--is that of any interest?

More like a quantile regression plot. Hi all, I have done scatter plot: plot(x, y). Now I wanted to do binned quantile plots... can ggplot2 help me? For example, we bin x data into 10 bins. For each bin, we draw the 10 deciles of the corresponding y data in that bin as points/dots. And then accross all bins, we would like to connect the corresponding decile points/dots together(something like equi-quantile or equi-decile curves)... How do I do that in R or ggplot2? Is there an existing function/command that can do this? I'm not aware of it if there is. But I agree that it can be a very informative display of data. I do such plots on data structures generated using tapply with age, sex categories and quantile() to generate a value. It gets kind of hairy with the list structure that results but if you have a more simple data situation it will probably be more straightforward, and you should post it.

Re: [R] Averaging uneven measurements by time with uneven numbers of measurements

Re: [R] Averaging uneven measurements by time with uneven numbers of measurements
In your first request for help you said, How do I average the measurements by every 30 minutes? With 25000 readings over three days, it looks as if you are getting readings just about every second. Okay, why don't you use the first reading as your initial weight, w0. Then subtract each succeeding reading from that to obtain the amount of feed dispensed. Now plot that value every 30 minutes. If you are interested in the variation of feed dispensed over a half hour interval, that can be easily obtained by accummulating those half-hour readings. -- Clint BowmanINTERNET: cl...@ecy.wa.gov Air Quality Modeler INTERNET: cl...@math.utah.edu Department of Ecology VOICE: (360) 407-6815 PO Box 47600FAX:(360) 407-7534 Olympia, WA 98504-7600 USPS: PO Box 47600, Olympia, WA 98504-7600 Parcels:300 Desmond Drive, Lacey, WA 98503-1274 On Thu, 5 May 2011, Schatzi wrote: I do not want smoothing as the data should have jumps (it is weight left in feeding bunker).

Thanks for taking the time to consider the problem. I realize the procedure

Anyway, I tried your suggestion adding a { in front of the for loop and a

Depending on where your data came from, you could get caught by the fact that the above
is really ...na.strings=-999... and that is not going to work if the actual
code is (say) -999.00.
Another straightforward option is dat0[dat0 == -999] - NA

Re: [R] spacing of color key in filled.contour
I've gotten good results using the sine function to map colors. For example, when plotting x, map the range(x) to (-pi/2,pi/2) which the sine will transform to (-1,1), then add 1 and multiply by half the desired number of colors. Now the integer values will pick the colors and give a pleasing display. If the squeeze is taking place only over one of the tails (which sounds like your case) map the range from (0,pi/2) or (-pi/2,0) and make the necessary scaling adjustments to cover the number of colors desired. Essentially, you are transforming the color mapping instead of transforming your data.

Re: [R] Remove 100 years from a date object
There still may be a problem if the dates go back far enough, e.g., 1909. Is '09' 1909 or 2009? No matter what, you have to decide which values need 1900 added and which need 2000. I'd split the date on the delimiter '.', decide whether to add 1900 or 2000, and then paste them together and then as.Date().

I thought of trying to take off some time i.e. as.Date(camCD$DoB,format=%d.%m.%y) - 100*365 But that doesn't seem to work out correctly. Any ideas how to do this? Normally to adjust dates you can use as.difftime() and do arithmetic, but a year is a variable thing (can be 365 or 366 days) so you cant make a difftime of years. Days are variable things if you worry about leap seconds... Also, you could end up with an invalid date if you have 29-Feb-2000 and 29-Feb-1900. One wasn't a leap year... A solution minus those caveats is to convert to POSIXlt and adjust the $year element: dob=27.02.37 as.Date(dob,format=%d.%m.%y) [1] 2037-02-27 dobp = as.POSIXlt(as.Date(dob,format=%d.%m.%y)) dobp$year = dobp$year - 100 dobp [1] 1937-02-27 UTC as.Date(dobp) [1] 1937-02-27 although it might be easier to paste a '19' into your character variable paste(substr(dob,1,6),19,substr(dob,7,9),sep=) [1] 27.02.1937 and then do it the way you started.

Pipits is the response variable (it is the number of birds counted at
each survey site in each year) and year is the independent variable.
If you plot it in R (plot(year,piproute,pch=19)), you'll see that the
relationship looks like a quintic polynomial.
Initially I was trying to fit this curve using an iterative equation,
but it's not working. I suspect that the curve-fitting equation itself
is inappropriate (it's a modified version of the logistic growth
equation). Now what I'd like to do is identify the 3 break/inflection
points in the population trend. That way, I can make an argument that
the break points corresponded to shifts in government policy with
respect to land use management. I've been looking at the segmented
package, and initially I looked at change.pt test in the circ.stats
package (which is inappropriate b/c my data is not amenable to
circular statistical analysis). Any ideas on what I could do would be
appreciated!

Re: [R] two questions for R beginners
I started using statistical software with the commercial product S+ when I obtained a new HP735 workstation. We kept the S+ license going for a number of years until I heard about R. It was an easy transition and because I have been proficient in fortran and perl, the scripting came naturally--except for some syntax similarities/differences between perl and R interacting with a natural tendency towards dyslexia. I especially like that I can slice and dice the data to ferret out relationships e.g., concentration by hour of day, by month, by wind speed, by wind direction--love those boxplots. I also find that even the default settings produce some pretty attractive plots that are useable in many settings--I've also produced some pretty awful ones. And the price always reminds me that I need to find every way possible to contribute to the overall good--I've forgotten too much of my fortran and C programming skills to contribute directly to the R Project.

Re: [R] Temperature Prediction Model
Aneeta, My gorilla and mouse analogies were referring to the magnitude of the disturbance and also to its time signature. Are you only interested in the large disturbance which is abrupt (the gorilla)? Or do you also want to be able to detect the more surreptitious attack which may be quite gradual (the mouse)? You will want to define the magnitude (and perhaps the associated duration) of the smallest disturbance that would be important. I would look at the entire data set to see what would be the likelihood of detecting such a change given the noise in the temperature data. Or alternatively, use the global analysis to help define the minimum disturbance that could be detected. Then see what can be done with just the first 7 days of data (or for matter the past 7 days regardless of when they occur). I applaude your goal of looking at each sensor without referring to other nodes but I think I would develop the analysis by looking for anomalies in one sensor's data when compared with other sensors and then focusing on those periods to determine an approach for detecting a disturbance. Because you are looking at 7 days, should we assume that you expect a day-of-week dependence? If so, I'd be more comfortable if you used more than one week to develop it. I fear that you've gotten me quite interested in this analysis, good luck.

We expect that if someone has learned a skill, they will prefer to engage in other behaviors where they can successfully use that skill. Upon this easily understood foundation rest the fortunes of many. Thus two of those entities, let us call them A and M for the purposes of discussion, spend a great deal of time and effort attempting to differentiate their interfaces from each other so that having trained their users, those users will be reluctant to switch to the competitor. However, they must remain similar enough so that the switch from the competitor is not impossible. Such is the dispiriting triumph of form over substance in interface design. Both have yet to abandon such atavists as myself who prefer to type rather than fiddle with a pointing device, though they try hard to convert us. A somewhat smaller organization that I will label G seems to have decided that it can build a user base by sticking to the arcane typoglyphics of the VT-100 era and enticing the largely amoral digirati with moral suasion. Now that's madness. Jim Once again, I cannot resist citing the immortal quote (from Charles Curran, of the UK Unix Users Group): I can touch-type, but I can't touch-mouse That's a strange disability. It took me several months to learn to touch-type (and years later I'm still not very good at the top-row numbers or the special symbols on them), but I memorized the location of the two buttons on my mouse in no time at all.

Re: [R] How do I plot a line followed by two forecast points?
Because you know a priori the dates associated with your forecast points you could use the col= in the plot function to change colors for the last two points (may require some mathmatical gymnastics to specify the colors desired--I've set up a vector and created an index from either the x or y values to obtain the desired effect).

dev.off()
rm(dens,xlimit,ylimit)
I barely managed to get the ratio I want for the graph

But still when I change the width in the poscript command from 12 to 20
for instance, it doesn't change anything... why?
BTW how do I stop the pipe between a poscript file and R without closing R?

I think you should consider using dev.copy2eps(), which will give you more

Re: [R] 3D trajectory plot?
In reading this thread the thought popped into my head. A smooth representation of the trajectory defined by the data in Chris's message from Wednesday is very similar to the guidance problem of a rocket. I believe that guidance engineers use Kalman filters to smooth out noisy data to generate the control signals to keep the missile on course. Would an such an approach work here to produce a smooth estimate to the trajectory described by the data?
