Re: [R] Unicode chars
Thank you for the reply I tried xeLatex at least once and possibly twice
and it failed to compile
I now tried it again and found that I had missed the inputenc error when
I tried before.
After removing the line it now compiles.
Thank you
Regards

Are you aware that pdfLatex does not support Unicode? You need to use
xeLatex. But I don't use Sweave, so I don't know how you go about making
that choice.

Is there a way of adding "sanitizing" code in the output before

Re: [R] Getting minimum value of a column according a factor column of a dataframe
The requirements keep being clarified and it would have been very useful to
know more in advance.
To be clear. My earlier suggestion was based on JUST wanting the minimum for
each unique version of Code. Then you wanted it in the original order so that
was handled by carefully making that a factor column in the order you wanted
the output. Now the request is to throw back in ALL the columns for as many
rows as are deemed minimums.
So, not in any way demeaning the various methods others offer, I suggest you
look at database style joins. R has some in the core with names like merge()
and other packages such as dplyr have all kinds of variations on a theme.
In my case, you can extend the part of my code that makes this as a second
data.frame/tibble:
Code minQ
1 41003 0.160
2 8 0.160
3 41005 0.210
4 41009 0.218
5 41017 0.240
Call it df2 as in:
mydf.min <-
mydf %>%
group_by(Code) %>%
summarize(minQ = min(Q))
You now have the original thing I called mydf that has a column called Code and
lots of other columns and you have a smaller one with fewer rows and columns
called mydf.min and they share a single common column.
You want to merge these two using whatever kind of join makes sense. Dplyr
offers an inner_join(), left_join(), right_join() and full_join() and you can
tweak merge() and others to do similar things.
What you seem to want is to find all rows that share both a particular value
for Code and at the same time a particular value for minQ in one versus Q in
the other. You want to ignore all others. What gets returned can have all the
original columns and perhaps also the minQ column (which can be removed) and if
two or more rows in one grouping share exactly the same minimum, may get
slightly similar but different lines matched. Is that what you want? Do note
matching floating point equally can be dangerous but in this case since the
numbers were all just read in, should be fine.
You can play with it but I tried this:
test <- left_join(mydf.min, mydf, by=c("Code", "minQ" = "Q"))
The values returned (and not I added an 8 category earlier in my data) look
like this:
Code minQ Y M DNO
1 41003 0.160 81 1 19 7.17 2.50
2 8 0.160 81 1 19 7.17 2.50
3 41005 0.210 79 8 17 5.50 7.20
4 41005 0.210 80 10 30 6.84 2.60
5 41005 0.210 80 12 20 6.84 2.40
6 41009 0.218 79 2 21 5.56 4.04
7 41009 0.218 79 5 27 6.40 3.12
8 41017 0.240 79 10 20 5.30 7.10
9 41017 0.240 80 7 30 6.73 2.60
You can see there are three minimum rows for Code 41005 for example and the
join keeps them all.
You can trivially remove the minQ column by naming the original as Q or just
removing it. You can again reorder things if you wish including by sorting on
other columns ascending or descending using other functions/verbs.
As noted, this has to work for you with your larger code set and sometimes
complex enough such requirements can be done many ways as it can be as much art
as science. I personally would probably write most of the above as one long
pipeline looking a bit like:
mydf <-
read.table(…) %>%
mutate(Code=factor(..., levels=unique(...)))
result <-
mydf %>%
group_by(Code) %>%
summarize(...) %>%
left_join(mydf, by=c("Code", "minQ" = "Q")) %>%
select(-minQ)
And of course it may be better to use the new R pipe operator if your version
is new and so on, filling in whatever details make sense to you. At the end of
the pipeline, you might want to use verbs that sort the data as described above.
My guess is you will now tell us about yet another condition suggestions like
mine do not fulfill and I will likely then ignore …

;Dear all
First of all I appreciate you for the answers you have sent. I did the codes

days. The days that data were measured were different for each station, and due
to this reason I had different rows for stations. For example, station number
one (41009) had 158 rows and station number 2 (41011) had 113 rows. Note that
the station's codes are not in order format (e.g smallest to largest).

See ?Startup for various ways of automatically executing custom code at R start up. See ?setHook and ?.onLoad for how to run custom code when packages (like grDevices) are loaded.

Re: [R] Getting minimum value of a column according a factor column of a dataframe
Yes, Timothy, the request was not seen by all of us as the same. Indeed if the request was to show a subset of the original data consisting of only the rows that were the minimum for each Code and also showed ties, then the solution is a tad more complex. I would then do something along the lines of what others showed such as generating another column showing the minimum for each row and then showing only rows that matched their value in two columns or whatever was needed. As noted, keeping the output in a specific order was not initially requested. Keeping the data in some order is a common enough request but in this situation, I suspect the order many might want would be the one showing the minimums in order, not the codes in the original order. -Original Message- From: Ebert,Timothy Aaron Sent: Thursday, August 25, 2022 11:59 AM To: avi.e.gr...@gmail.com Cc: R-help@r-project.org Subject: RE: [R] Getting minimum value of a column according a factor column of a dataframe My assumption (maybe wrong) was that we needed to keep the other variables.

Re: [R] Getting minimum value of a column according a factor column of a dataframe
The order of the rows returned by summarize is controlled by the levels of
the factors given to group_by. If group_by is given character columns
instead of factors, it converts them to factors with the levels being the
sorted unique values of the character columns. Convert you character
columns to factors with the desired levels to get the order you want.
E.g.,
> d <- data.frame(charGroup=rep(c("Small","Medium","Large"),3:1), x=101:106)
> d$factorGroup <- factor(d$charGroup, levels=c("Small","Medium","Large","X

Re: [R] Getting minimum value of a column according a factor column of a dataframe
Hello, Inline. Às 16:37 de 25/08/2022, avi.e.gr...@gmail.com escreveu: I read all the replies and am not sure why nobody used what I see as simpler and more direct. Assuming the ORDER of the output matters, it tends to be controlled by the order of the factor called Code so I have simple code like this: --- # Load required libraries library(dplyr) # Simulate reading in from a file by using in-line text version file_contents <- 'Code Y M D Q N O 41003 81 1 19 0.16 7.17 2.5 41003 77 9 22 0.197 6.8 2.2 41003 79 7 28 0.21 4.7 6.2 41005 79 8 17 0.21 5.5 7.2 41005 80 10 30 0.21 6.84 2.6 41005 80 12 20 0.21 6.84 2.4 41005 79 6 14 0.217 5.61 3.55 41009 79 2 21 0.218 5.56 4.04 41009 79 5 27 0.218 6.4 3.12 41009 80 11 29 0.22 6.84 2.8 41009 78 5 28 0.232 6 3.2 41009 81 8 20 0.233 6.39 1.6 41009 79 9 30 0.24 5.6 7.5 41017 79 10 20 0.24 5.3 7.1 41017 80 7 30 0.24 6.73 2.6' mydf <- read.table(text=file_contents, header=TRUE) # Group the results and provide a summary of anything you # want calculated by group: mydf %>% group_by(Code) %>% summarize(minQ=min(Q), meanQ=mean(Q), maxQ=max(Q), sdQ=sd(Q)) -- Shown as a data.frame, the result is: Code minQ meanQ maxQ sdQ 1 41003 0.160 0.189 0.210 0.025942244 2 41005 0.210 0.2117500 0.217 0.00350 3 41009 0.218 0.2268333 0.240 0.009389711 4 41017 0.240 0.240 0.240 0.0 You can remove all my extra code to just get the minimum: mydf %>% group_by(Code) %>% summarize(minQ=min(Q)) %>% as.data.frame Code minQ 1 41003 0.160 2 41005 0.210 3 41009 0.218 4 41017 0.240 The codes are shown in the same order as the data as it was made into a factor from raw data in that order. I may have misunderstood something as others provided an assortment of methods that, to me, seem less direct. The summarise/summarize function in dplyr was specifically designed to make a summary as requested, and grouped if preceded by a request. Yes, I agree with you. In the raw data the Code is already ordered so it doesn't matter if it is not addressed in the aggregation code. But from the OP's last post I conclude (wrongly?) that in the original data this need not be the case. Hence the double order() in my last post. I wonder (a) if it's really necessary and (b) if it would make a difference if the aggregated output is sorted.

You could try to automatically clean the code, by using
?iconv, say. But the results by not be satisfactory,
depending on what characters were used.
Sweave itself does not compile the LaTeX code. If you
run (in R)
Sweave(, encoding = "utf8")
then it will produce the TeX file, which you can then
compile via LuaLaTeX or XeLaTeX [see
e.g. https://www.ctan.org/pkg/lualatex-doc].
For instance, on the command line, just say
lualatex
or another programme (such as latexmk) that your TeX
distribution provides.
If this is a vignette, you can specify a Makefile, see
https://cran.r-project.org/doc/manuals/R-exts.html#Writing-package-vignettes
