Hello everybody, I frequently have to produce barplots from variables the natural variation of which is far away from zero. A typical range would be, say from -16 to -28. So, the following example should give an "honest" presentation: x<-c(-20,-22,-21,-28) barplot(x,beside=T,ylim=c(-18,-30)) But using anything else but "0" for the first element of ylim leads to strange

Does anyone know of any SOM library for R? or any stand alone freeware? A search from google returns SOM_PAK 3.1 developed at Helsinki University of Technology. Is there newer version?

Hi everybody ... I have to perform Hotteling's T^2 Test - more generally a MANOVA - on a set of data. Is there a (simple?) possibility to do it in R? The somewhat obvious way to do it would be > summary(aov(Y ~ x1 + x2 ... + xn)) where Y would be a two-column matrix. But this does not work in any possible combination of matrix or factor dimensions! Is it principally not possible

Hello everybody, since I installed R-0.90.0 (Linux 2.0.25) I have problems with generating printable output with 'help()'. Default output to the terminal ('echo $PAGER' gives 'less') works o.k.. When invoking 'help(topic,offline=T)' all the usual procedures seem to start: 'top' reports invocation of latex as well as of dvips. But after finishing there is

Hello everybody, I observed some strange behavior of R (0.64.1/Linux 2.0.25) when trying to use FORTRAN-libraries. I downloaded "ALGORITHM AS 304" from StatLib. All I changed at the code, was to substitute "REAL"-routines by "DOUBLE PRECISION". Compiling went o.k. ... > g77 -fpic -O2 -shared -o rtest.o fisher.f ("g77 --version" gives 2.7.2.1)

Hi , I ''ve got a trouble with using R. When I want to load a file that contains 93 thousand raws and 22 colums of data (essentially float) R shows me this error message "heap size trouble" Does anyone could tell me what parameter shall I precise before launching R in order to load my big file. Thanks a lot -------------- next part -------------- A non-text attachment was

Hello again I'm trying to put error bars onto a barplot. I've tried something that Bill Simpson suggested a while ago, ie: x<-c(1,2,3,4,5) y<-c(1.1, 2.3, 3.0, 3.9, 5.1) ucl<-c(1.3, 2.4, 3.5, 4.1, 5.3) lcl<-c(.9, 1.8, 2.7, 3.8, 5.0) plot(x,y, ylim=range(c(lcl,ucl))) arrows(x,ucl,x,lcl,length=.05,angle=90,code=3) #or segments(x,ucl,x,lcl) but I can't get it to work on a

Dear friends. Below is ouput directly from the help on qqnorm.lme.html It do not seem to work as expected - on win98, R 1.1, although the regression is undertaken, so qqnorm misunderstands, or what ? library(nlme) data(Orthodont) fm1 <- lme(distance ~ age, Orthodont, random = ~ age | Subject) # normal plot of standardized residuals by gender qqnorm(fm1, ~ resid(., type = "p") | Sex,

Johannes Huesing sent a message to stat-lisp-news at stat.umn.edu regarding an article in Linux-Magazin (German) on statistical software for Linux. I enclose excerpts. Can anyone summarize what was said about R in the article? If there is a web site for the article I would appreciate learning of the URL. I must admit, though, the my abilities in German are much less impressive than the

Dear R-experts, I have a problem to formulate non linear mixed effects when more than one explanatory variable is present. I'm using R 1.1.1 under Linux. The version number of the nlme library is 3.1-7. "help(nlme)" says that among several possibilities it is possible to code fixed effects according to fixed = a1 + a2 + ... + an ~ X1 + X2 + ... + Xm where the left hand side

Dear R-helpers, I frequently run into problems when I modify elements of factors (R 1.0.0, Linux 2.0.25). For example, after splitting a data frame accordinng to whatever criterion, it might well happen that not all levels of a factor are present in all new data frames. However, R doesn't seem to care about. When performing some kind of analysis seperately on the new frames, each time the

g'day R friends, I was hoping someone could provide me with advice as to my dysfunctional 'arrow' keys. Instead of browsing thru my command history they just move my cursor. What have I done wrong?

Howdy, I looked at the references in the R and S-Plus literature to find a good introduction/reference to GLM.

I have a probably very naive question about the R anova/aov functions: I've found in several text books with descriptions of anova procedures that, in nested anova (specifying the model "X~A/B", B being a factor specifying treatments, and A groups of samples within each treatment), the mean square for "among treatments" is divided by the mean square "within treatment

Hello, I realize this is probably a dumb question, but I think there must be an easy way to do this with R and I was not able to find it in the doc. I have a table (read from a file with read.table), with two factor columns, table$A and table$B, and a numerical column, table$X. I wish to make a boxplot of (table$X ~ table$A) for a given value of B. Is there a way to express this with a

Hi, is the following possible - in a given session I make a lot of objects and save when exiting. Usually I note down seperately what each object is about. Is it possible to attach data to any object which would essentially be a short note explaining the meaning of it?

Dear R-users and R-developpers, I've not been able to find 3d graphics in R, like Splus spin() or brush().

Hello out there, my first try to install a package (e.g. ctest from CRAN) didn't succeed; looking at the error messages I think it must be a configuration problem of my machine, but as I'm not very experienced I would be glad if someone could give me a hint ... R's version is 0.63.0, my i386-Linux is kernel 2.0.35. I hadn't had problems to compile R, and R itself seems to work.

I noticed that congigure reported libpng as "not found" although a recent version exists. Further looking into this issue told me, that the test failed because the test from R.m4 AC_CHECK_LIB(png, png_create_write_struct, [ BITMAP_LIBS="${BITMAP_LIBS} -lpng -lz" AC_DEFINE(HAVE_PNG) ], , ${LIBS}) ], AC_MSG_RESULT([no])) ]) did
