Hi colleages! I want to import data from ms-excel and other spreadsheet formats (lotus, etc). Does exist any way to do it within R? The main problem is that many spreadsheet data use comma as decimal separator and not the point as needed in R (and many software for Linux), so importing data first as a tab separated values does not solve this problem. Thanks, Tom?s Revilla

Hello, Sorry about the last email, I just found the shortcutkey for sending, by mistake :-( OK. I am a windows user and I wanted to instal emacs. However, went to speak with the information staf on the institut and they told me that that is a bit problematic sometimes, and that there is a free soft that could do a very similar job which is crimson... This is like a note pad, but highlights the

Dear collegue, I have some questions about lattice graphs: 1. How can I introduce different lines in different graphs, from the same page? For example, in the upper row of graphs, I would like to have a line at 0.5, in the middle one at 0.3, and in the lower at 0.1. I am using panel.abline, but I can only make it appear in all the graphs, not in some of tham only... 2. Is it possible that the

Dear R users, I am trying to produce an image plot, that represents the proportions of a factor (z variable), so that the number of squares of each colour represents each factor level, with the respective label inside (sorry for the crap English). # Something like this: kk=data.frame(fact=letters[1:10], freq=c(5,1,10,2,10,7,5,10,30,20)) # factor and respective frequecies res="a" #

Dear R users, I have a problem in the configuration of R: I just changed university, and my conection to the net is via a password, which permits me to access the packages with no problem via the internet explorer (version 6).

Dear list members, I am trying to make a clean up on my computer (windows problems, off course), and I wanted to remove some libraries that I have installed in R, which have been hardly used. Is there any way to see how often each library is used by us? I have many that I am not sure... because they can be used with other packages, etc. Thank you very much in advance, Best wishes, Marta

Dear R-list members, I am calculating the linear extrapolation for a data set, using the function found in Hmisc. x=c(0.0265,-0.0003,0.0142,0.0263,0.0634,0.1145,0.2504) y=c(58,107,152,239,362,512,724) x1=0.0393216 approxExtrap(x,y,x1, method="linear") approx(x,y,x1) #to see what is happening: plot(x, y, typ="o") abline(v=x1, col=8) Which gives x=0.03 and y=163, instead of

Dear list members, After looking in the www, I found this subject has been in discussion previously on the mailing list, although I could not solve it. I also found two wikis, but similarly, could not reach a conclusion. I need to re-produce my figures with 1200 dpi, in tiff format, for a journal (off course :-s).

Dear R list, I have been trying to do a linear model, extracting the effect of a covariate.... and the results do not match, when I do it with other programs (e.g. minitab).... so it is obvious that I was doing something wrong. Whan I do it with minitab, I have this results: (sector is a factor and depth is the covariate): Source DF Seq SS Adj SS Adj MS F P

Hi Now a more theoretical question. I have two correlation matrices - one of a set of variables under a particular condition, the other of the same set of variables under a different condition. Is there a statistical test I can use to see if these correlation matrices are "different"? Thanks Mick

I'm coming out with all the classic problems today ;-) Can anyone tell me how to change the column names of an already existing data frame? I've read the docs for ?data.frame and ?as.data.frame but can't figure it out. I want to make a new data.frame from some of the columns of an existing data.frame, but when I do that, the new data.frame columns have the same names as the old
