[R] General Copula theory
Hi everyone! Firstly, let me specify that I an new to copula theory, so be gentle! I have two data sets containing wind data for 14 years, and I am to use Gumbel marginals and a Gumbel copula. The question is, how will I generate data from the marginals? I have 14 years of data (4 observations each day), so I have taken the maximum of each year (eliminating seasonality) and then found the parameters of the corresponding Gumbel distribution. But then what? Should I generate n values of Gumbel distributed data, get uniform values by the inverse cumulative, and then put these into the Gumbel copula? I guess this have to be wrong, but I just can't seem to find a good procedure on this topic.

So the first UK study with a median age of 25 is going to be used to estimate prevalence over a range of ages? You are going to have to make some very strong assumptions here which I personally would not want to make. I'm a little confused by this. In my understanding, the mixed-effects model does not do that. The slope of the relation between age and prevalence will be estimated from the full pool of studies, and the country-level random intercept will be estimated from all studies in the country. So the assumption here is that the relation between age and incidence is the same in every country, which is quite reasonable. Of course, there will be more uncertainty with the estimation of the random intercept if there is few studies in a country, or if there is a strong inter-study variance in a country. This will influence the confidence interval of the random intercept, and so the CI of the predicted prevalence for this country. Your studies are ecological. You are estimating the relationship between prevalence and being in a study of median age X which is not necessarily the same as the relationship between prevalence and being a person of age X. Is there any possibility that in the real dataset you can fit your model to those studies which do provide age-specific prevalences and then use that to impute? You do not say when these studies were published but I would ask the authors of the primary studies if they can make the information available to you. You may have already done that of course. I referee quite a few papers on systematic reviews and my impression is that some authors are amenable to doing the work for you. You mileage may vary of course. Yes, it would be easier to have prevalence for age subgroups of studies, but we did not have access to that information for most studies even after contacting the authors. *Standard random-effect meta-analysis* with package meta. I used metaprop() to get a first estimate of the prevalence in each country without taking age into account, and to obtain weights. As expected, heterogeneity was very high, so I used weights from the random-effects model. Which will be nearly equal and so hardly worth using in my opinion but again your mileage may vary. The weights from the random-effects method were actually far from equals, as sample size was highly variable between studies. With the RE method, small studies have much more impact. I am afraid that is the way with systematic reviews, you can only synthesise what you find, not what you would like to have found. Anyone who has done a review will sympathise with you, not that that is any consolation. I'm not sure I'm following your point. My objective is to synthesise the included studies, while taking the age factor into account, since it is strongly linked to prevalence and very heterogeneous. The alternative is to only include studies with low median age, but I would lose a lot of information.

[R] StatET and R 3.1.0
R-helpers: I posted a message to the statet listserv, but I thought I'd ask here as well since it is one of the major R developer environments-- has anyone gotten the StatET plugin for Eclipse working with R 3.1.0 yet? Any tricks? I did manage to get rj updated to 2.0 via: install.packages(c(rj, rj.gd), repos=http://download.walware.de/rj-2.0,type=source;) But the plugin is throwing an error (using the last maintenance update at http://download.walware.de/eclipse-4.3/testing): Launching the R Console was cancelled, because it seems starting the R engine failed. Please make sure that R package 'rj' (1.1 or compatible) is installed and that the R library paths are set correctly for the R environment configuration 'R'. --j -- Jonathan A.

[R] sink() and UTF-8 on non-UTF-8 systems
Hi! In the series dealing with encoding madness on hostile systems, I'm looking for help as regards capturing R UTF-8 output on a system where the locale is not using UTF-8, and where some characters cannot even be represented using the locale encoding. The case I have in mind is printing a character vector with Russian text to the R Commander output window on an English/French (CP1252) Windows system. Here's a code snippet illustrating the problem: \U41F [1] П # OK con - file(open=w+, encoding=UTF-8) capture.output(cat(\U41F), file=con) readLines(con, encoding=UTF-8) [1] U+041F # Not OK (same result without specifying 'encoding') Now I have read ?sink and it is quite explicit about how this works: If file is a character string, the file will be opened using the current encoding. If you want a different encoding (e.g. to represent strings which have been stored in UTF-8), use a file connection — but some ways to produce R output will already have converted such strings to the current encoding. The last words seem to apply to the case above, i.e. somewhere in the process the UTF-8 string is converted to the locale encoding. Is there any solution to get the correct output?

[R] partitioning around medoids
Hello I am running some k-medoids analysis to see if that algorithm will work better on my dataset compared to the k-means I have been using so far. When running k-means I used to specify the nstart option, equal to a certain number, depending on how many random sets of clusters I wanted. Could anybody tell me if I need to use, or if there is, an equivalent option for the pam() function? pam(x,5) is what I have put together so far. Also, any suggestions for what I might implement there?

[R] Save file as Fixed Width using sprintf()
I have working code to write a file out as fwf as shown below. I have one
question to try and automate this I cannot get to work.
I am generating thousands of data files for a simulation to be run outside of R
and each file varies in its dimensions. So I am trying to write code that can
write the fwf based on the dimensions of each file generated as shown below. I
have commented this code with an example to show where I am stuck.
### Create a sample data matrix
myMat - matrix(rnorm(9), 3,3)
### Create the vector of format strings to be equal to the length of the
columns in myMat
aa - rep('%4f', ncol(myMat))
xx - paste(aa, sep='', collapse='')
### Now I could just do this below and it works
(out - sprintf(xx, myMat[, 1], myMat[, 2], myMat[, 3]) )
out - as.matrix(out) # convert to a character matrix
dimnames(out) - list(rep('', nrow(out)), '') # blank row and column names
noquote(out) ## sink this file to a directory
But, the fact that the dimensions of my matrix vary at each iteration means I
need to automate this part in the sprint().
myMat[, 1], myMat[, 2], myMat[, 3])
I think that's needed because something like the following does not work
(out - sprintf(xx, myMat[, 1:3]) )
So, I thought about trying smoething like this
cols - paste(paste('myMat[, ', 1:ncol(myMat), sep=''), ']', sep='')
cols - paste(cols, collapse=', ')
But, this is a string with quotation marks, so I thought using cat() might
work, but it does not
(out - sprintf(xx, cat(cols) ) )
Anyone have a suggestion for the right way to do this, this is getting messy.

Re: [R] Save file as Fixed Width using sprintf()
Try this. It creates a 'list' that are the parameters for sprintf. It
writes out the file that I attach as the dump:
### Create a sample data matrix
myMat - matrix(rnorm(9), 3,3)
# create the format required -- make sure it is wide enough
# for 'fixed' width
xx - paste(rep(%8.2f, ncol(myMat)), collapse = '')
# create a list for 'do.call(sprintf'
callList - vector('list', ncol(myMat) + 1)
callList[[1]] - xx # store in the format
# add the columns to the list
for (i in seq(ncol(myMat))) callList[[i + 1L]] - myMat[, i]
callList # print it out
result - do.call(sprintf, callList)
# write out the data to a file
writeLines(result, '/temp/file.txt')
Here is what is in the file:
-0.390.45 -0.44
-0.82 -0.68 -0.43
2.05 -0.850.61

[R] R, RStudio, and a server for my iPad.
I bemoan the fact that I can not run R or Rstudio on my iPad. A possible work around would be to set up a server (probably under Linux), and get the server to present a web page that to would allow me to run R on the server. I have searched the web for a clear, simple answer on how to do this but can not find one. There are answers, but not for someone who has not built a Linux server. Can someone provide either a reference to, or a short explanation of how I can build the server, get R or RStudio to run on it, and get the server and its R or RStudio program available to me on my iPad?

Re: [R] R, RStudio, and a server for my iPad.
I see. You might indeed be over thinking it ... since everything is installable by the package manager for the flavor of linux you choose, it should actually be relatively straightfoward (although if this is your first time setting up a linux box, it can take a few tries). I'll assume you are using an ubuntu server. There are two things you can do to get one (1) Get yourself a spare CPU. Blow out the OS on it, and setup vanilla ubuntu; or (2) Rent an ubuntu server from somewhere like linode.com Then: (a) Install R on it, by following the instructions here: http://cran.rstudio.com/bin/linux/ubuntu/README.html Which boils down to basically: (i) adding the appropriate line to your `/etc/apt/sources.list` given the version of ubuntu you installed (saucy, quantal, etc) ; and (ii) Running the following from the terminal: sudo apt-get update sudo apt-get install r-base sudo apt-get install r-base-dev (b) Install RStudio Server. Start from the Download and Install section here (since you already installed R): https://www.rstudio.com/ide/download/server Then go here: https://www.rstudio.com/ide/docs/server/getting_started If you've set this up on your own machine (option (1) from above) then you have to figure out how to connect it to the internet if you want to use it from anywhere outside of your LAN. It might seem like a lot of work, but as mentioned above -- since these packages are available by the system's package manager, all of the dependencies (like apache (if you need it)) will be installed for you if you follow the (presumably correct) installation instructions from RStudio. === An even easier setup === Just realized that there is 3rd route. You can save yourself a lot of time by using an already built amazon machine instance that the bioconductor folks have setup for you. Look at the instructions here: http://www.bioconductor.org/help/bioconductor-cloud-ami/ If you follow along (you'll need an amazon account), you can rent a machine and have it loaded w/ RStudio Server as well as some bioconductor-specific libraries to get you started (by using the bioconductor AMI). Once you have that up, you can connect to the server running on Amazon's cloud via your web browser on both your CPU (to make sure it all worked) then using an iOS device. This would be a very easy way for you to see if taking one of the 2 avenues of setting up RStudio Server yourself would be worth the pain.

Re: [R] R, RStudio, and a server for my iPad.
Even if you do get Rstudio running on a server, unfortunately it won't
help. The ipad doesn't support quite enough html to get a fully
functional Rstudio interface - almost everything works but you can't
type anything :/ It would be possible to fix this, but fundamentally
we don't believe that the Rstudio interface is the right choice for an
ipad.

Re: [R] Label axis tick marks with a simple function of axis value
You're on the right track, I think. Try this example: plot(21:30, xaxt='n') labs - paste(1:10,'units',sep='\n') axis(1, at=1:10, labels=labs, mgp=c(3, 1.75, 0) ) Documentation for the mgp option is found in ?par and it's not something that I would expect someone new to R to find easily. In my opinion, the philosophy of R is that a lot of basic tools are provided, and from them the user is expected to customize and construct precisely what they want. Although, many of the R packages available from CRAN exist because someone wanted to pre-write some fancy options for users to choose from. Of course, since all the units are the same in my example, it might make more sense to put the units in the axis label, such as: plot(21:30, xlab='Units') Note a little trick in that in the above example that might be unexpected. I didn't supply both x and y. When only one of them is supplied, it is interpreted as being y values. Since there are 10 of them, it is as if it were: plot(1:10, 21:30) -- Don MacQueen Lawrence Livermore National Laboratory 7000 East Ave., L-627 Livermore, CA 94550 925-423-1062 On 4/9/14 6:17 PM, Hurr hill0...@umn.edu wrote: What we've covered so far is of great value.

You can not type _anything_ into Rstudio if you connect to it on the

Even if you do get Rstudio running on a server, unfortunately it won't
help. The ipad doesn't support quite enough html to get a fully
functional Rstudio interface - almost everything works but you can't
type anything :/ It would be possible to fix this, but fundamentally
we don't believe that the Rstudio interface is the right choice for an
ipad.

Re: [R] R, RStudio, and a server for my iPad.
Hadley, Thank you for the clarification! This is too bad as I had thought that given that RStudio server followed a web-based rather than a client-server paradigm that I could use my iPad to access an RStudio server and thus have access to R. Perhaps I wasted a loot of on my iPad . . .

[R] invalid multibyte string at 'b0C'
R 3.0.2 OS X Mavericks Colleagues I have a file that I converted from SAS (sas7bdat) to CSV (filename: ORIGINAL.csv). I try to read it with read.csv and I receive the error message: Error in type.convert(data[[i]], as.is = as.is[i], dec = dec, na.strings = character(0L)) : invalid multibyte string at 'b0C’ The problem resolves if I delete a single character from each of lines 2 and 4 of the file (filename: FIXED.csv) readLines can read both files without problem and displays the offending character as: \xb0 which appears to be a degree sign. I also tried: read.csv(textConnection(readLines(“ORIGINAL.csv”))) and encountered the same error message. In the past, I have encountered the same problem with Greek symbols (e.g., mu) and other special characters. Short of editing the input file, is there a simple solution within R so that I can read the input data into a dataframe? One possible (but ugly) solution would be: TEMP- readLines(FILENAME) TEMP- gsub(offendingcharacter, replacementcharacter, TEMP) However, this would require that I find all possible offending characters and the corresponding replacements.

Re: [R] R, RStudio, and a server for my iPad.
David, Thank you for your assistance. I have, in fact been able to get things to work, at least when my iPad is on my local network. I had to do the following: (1) install Linux (I used linux Mint) on a computer on my LAN (2) install R on the linux box (accomplished using the Mint package manager) (3) install Rstudio and RStudio server on the linux box (accomplished using the Mint package manager) (4) obtain the linux computer's internal IP address (obtained using ifconfig command entered at a terminal). The internal IP address was 192.168.0.101 (5) use a browser on my iPad (I used google chrome, I believe firefox would also work) to connect to the linux box, requesting a connection using port 8787 In the brower I entered http://192.168.0.101:8787 This works like a charm; I can now control RStudio, which runs on the Linux box, by typing on my iPad. I thus gain access to RStudio on my iPad, RStudio works exactly as if it were running directly on my iPad, hooray! My remaining problem is to determine how I can gain access to the linux box from outside my LAN. I know the IP address of my cable router xx.xx.xx.xx (forgive me I am not listing my external IP address for security reasons), but I don't know how I can address the linux box from outside my LAN. Clearly I can't use 192.168.0.101 as it is an internal IP address, and I can't use the external IP address, xx.xx.xx.xx as it is the address of my cable box, not the address of the Linux box behind the cable modem. If I can figure how to address the linux box from outside my LAN my problem will be solved! If anyone can help me with this last problem I would be grateful. I know it is not strictly an R question, but in my case it is related to running R, at least on my iPad.

Re: [R] calling in inverted commas
Hi,
I noticed some special characters after sending.
It should be:
toreplace - gsub(.*\\.pl\\?(west\\=.*south=.*)\\params.*,\\1,Url1)
end - gsub(.*south=.*(\\params.*),\\1,Url1)

Dear useRs,
Here are three steps for downloading a file from a certain website in R. Here
you see that in URL command (west=68.25north=24.75east=68.25south=24.75)
are actually the first and second column values of 1st row of a matrix called
df2 (300 rows and 2 columns). more precisely, df2[1,][1]=68.25,
df2[1,][2]=24.75.
Is there a way that I can make a loop so that remaining rows and columns get
inculcated in the link as such and then get saved at the desired mentioned
location in 300 different text files?

Any suggestion?
Thankyou very much in advance,
