similar to: Font size of axis labels

Hi all, Assume I have a data frame with numerical and factor variables that I got through merging various other data frames and subsetting the resulting data frame afterwards. The number levels of the factors seem to be the same as in the original data frames, probably because subset() calls [.factor without drop = TRUE (that's what I gather from scanning the mailing lists). I wonder if

Is there a way to adjust the font size for axis labels when using persp()? The parameter cex works for adjusting the global font size, but I can't seem to make cex.lab or cex.axis work for adjusting these values independently. Or, is there a preferred method for making surface plots in R? I'm using R version 1.8. Thanks, Manuel

Hello, is there a R package that provides a log rank trend test for survival data in >=3 treatment groups? Or are there any comparable trend tests for survival data in R? Thanks a lot Markus -- Dipl.

hi using plot(..., las=1), i.e. horizontal axis labels, the labels on the y-axis jams if the heigth of the graphics windov becomes too low while both x-axis and y-axis kind of removes superflus lables with las=0 (default) is there a way to make plot behave alike with horizontal lables? regards s??ren

Dear R-users, is there any object-type or routine/function in R which can handle unequally spaced time-series data? I know that there is the library OSWALD for S-Plus, which is able to do so, but I was not successful in running it under R. Does anyone can help? Thank's in advance!

Hi, is there anybody knowing a possibility to produce a legend (describing the color scheme) in an image plot in R. In S-Plus this works using image.legend. Thank's in advance.

I was hoping that the following specification postscript(file="fig.ps",height=2,width=4) par(mar=c(5,5,2,2)+.1,mfrow=c(1,2),mex=.6) would yield the same scaling effect as postscript(file="fig.ps",height=2,width=6) par(mar=c(5,5,2,2)+.1,mfrow=c(1,3),mex=.6) but the fact is that the 'mfrow=c(1,2)' yields smaller plotting frame and bigger font size.

Dear R users, is there any possibility to get an object-name completion within the R command line (UNIX-version of R). As I got to know from the FAQ that this is possible from within Emacs (ESS), but without using Emacs?

I recently built R 1.6.2 on solaris 2.8 with gcc 3.2. Things seem to run OK, but using graphics causes R to core dump. (For instance, by using the plot() or hist() functions.) Sometimes I can see the graphics drawn before it actually core dumps. The core file shows a crash in Rf_gpptr. I'm quite new to R, so I don't know what info would be helpful for diagnosis. I'm including

Full_Name: Hilmar Berger Version: 2.4.1/2.6.2alpha OS: WinXP Submission from: (NULL) (84.185.128.110) Hi all, If I use tapply on an empty data.frame I get an error. I'm not quite sure if one can actually expect the function to return with a result. However, the error message suggests that this case does not get handled well. This happens both in R-2.4.1 and 2.6.2alpha (version 2008-01-26).

Hi all, I'm not quite sure if this is a feature or a bug or if I just fail to understand the documentation: If I use cor() with pairwise.complete.obs and method=pearson, the result is a scalar: ->cor(c(1,2,3),c(3,4,6),use="pairwise.complete.obs",method="pearson") [1] 0.9819805 The documentation says that " '"pairwise.complete.obs"' only

Hi January, I believe the root of the xlsx issue has been identified and a fix suggested by Tomas Kalibera (see https://github.com/s-u/rJava/pull/102). In a nutshell, Oracle Java on Linux modifies the stack in a way that makes it smaller and and the same time makes it impossible for R to detect this change, leading to segfaults. It is not clear to me that the same problem would occur on Mac,

Dear all, I did some more tests regarding the == operator in Ops.data.frame (see below).? All tests done in R 3.6.1 (x86_64-w64-mingw32). I find that errors are thrown also when comparing a zero length data.frame to atomic objects with length>0 which should be a valid case according to the documentation. This can be traced to a check in the last line of Ops.data.frame which tests for the

Hi, I would like to get from a plot the size of the symbols plotted. Imagine I have the following plot function : plot(1:2,1:2, pch=15, cex=4) I would like the get the values SIZE1 and SIZE2 so that if I plot the following rectangle : rect(1.5,1.5, 1.5+SIZE1, 1.5+SIZE2) then the size of this square is exactely the same as the one of the symbols that have been plotted. Thanks for any idea. --

Sorry, I can't reproduce the example below even on the same machine. However, the following example produces the same error as NULL values in prior examples: > setClass("FOOCLASS", +????????? representation("list") + ) > ma = new("FOOCLASS", list(M=matrix(rnorm(300), 30,10))) > isS4(ma) [1] TRUE > data.frame(a=1:3) == ma Error in

Hi, This is the first time I've posted, and I apologize if I formulate this incorrectly. I am analyzing data from a multi-region carrot variety trial. 35 varieties of carrots were grown in 3 randomized complete blocks in organic and conventional fields in Wisconsin, Indiana, Washington, and California. In this example I am comparing the heights of the carrot tops at harvest. In other

I think this is a known issue with Java messing with the stack, see e.g. http://r.789695.n4.nabble.com/Error-memory-exhausted-limit-reached-td4729708.html. I'll fix the infinite recursion caused by the methods package.

Hi Hilmar, weird. The memory problem seems be due to recursion (my R, version 3.3.3, says: Error: evaluation nested too deeply: infinite recursion / options(expressions=)?, just write traceback() to see how it happens), but why does it segfault with xlsx? Nb xlsx is the culprit: neither rJava nor xlsxjars cause the problem. On the other hand, quick googling for r+xlsx+segfault returns tons of
