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" #

Hello, I was simply doing a graph, but an error repeatdly occurs. Any idea why? (this only happens in the latest R version, I am a windows user). Thank you, Marta library(Hmisc) > example(xYplot) xYplot> d <- expand.grid(x = seq(0, 2 * pi, length = 150), p = 1:3, shift = c(0, pi)) xYplot> xYplot(sin(x + shift)^p ~ x | shift, groups = p, data = d, type = "l")

Hello, I am a newbie in R, I just did my first function, which works!!! And I would like to know, if I can create a directory in the library with my functions, in a way, which I could call that like we call the packages ? Can anyone help me?

Hello, I am a newbie in R and I am trying to create a function, that includes several functions inside. To avoid that everything stops if there is an error, I have this statement bla = function(....){ ... if(exists("last.warning")){rm(last.warning)} ... } inside the function, which if I use it normally, it works fine, but once I use it with the funciotn it gives me an error like:

Hello, I have a problem when doing gam (from gam library; I am using R 2.4.0, windows xp platform) When doing: example(gam) There is this error message (which also happens when using my data) ....

Hi I have a list with several data.frames, all with the same number of colunms but different number of rows, and I'd like to transform this list into a single dataframe.

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). I just updated R to R 1.81, and I cannot download nether upgrade packages (and many are not working with the update!!!). I have been looking in the help and emails, and

Dear R-users, I would like to change the labels size and format in the node ends of a dendrogram, how can I do it? How can I use different symbols/colors in each node ends ? I manage to do it with plot.cluster, but heat map uses plot.dendrogram. Can anyone help me please? thank you Marta [[alternative HTML version deleted]]

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

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 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). I am working on windows xp professional, R version 2.7.1, using x11 to open

Hello, Does anyone knows how to do the plots from discriminant analysis (lda and qda)? Is there any computed function to do the stepwise procedure? thank you in advance Marta

Your message seems unclear, and as evidence the respondents are giving various answers. You should provide a small sample of input and output data as it would look in R to avoid this kind of thrashing about. See [1][2][3] for guidance. Note that you also really need to figure out how to make sure your email program sends plain text, because HTML formatting WILL be stripped by the mailing list

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, I am pretty new to R and I would apreciatte very much your help to solve my problem. I have 40 csv files that have the same structure, and I want to merge them into a single data frame. I already have load and combined all the cvs files into a large list, and I created two filenames <- list.files('data',full.names=TRUE) All_data <- lapply(filenames,function(i){ ###read cvs

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
