Dear all, How could I use variables in a loop that their names are in a vector? For example: aaa <- 1:10 bbb <- aaa*2 ccc <- aaa+bbb varn <- c("aaa", "bbb", "ccc") m <- rep(NA, 3) for (i in 1:length(varn)) m[i] <- mean(varn[i]) # wrong thanks in advance Juli -- "Wars do not solve problems, wars generate even more problems"

Dear r-help, I have a radar data file in the following format: nrays for (1 to n_rays) { some_data_info for (1 to n_gates) { some_data_info} } N_rays=360 and n_gates=950 The data looks something like: Header line1 Ray1 header gate1 var1, var2,.....,varN ... gate950 var1, var2,.....,varN Ray2 header gate1 var1, var2,.....,varN ...

I am cleaning up the rms package to not export functions not to be called directly by users. rms uses generic functions defined in other packages. For example there is a latex method in the Hmisc package, and rms has a latex method for objects of class "anova.rms" so there are anova.rms and latex.anova.rms functions in rms. I use:

Hi Francois, Thanks for your quick response. Actually, I had already done that... sudo apt-get install libpoppler-cpp-dev Reading package lists...

Hi, I am trying to install pdftools package on R 3.3.1 (Ubuntu 16.04), but the following issue occurs: ------------------------- ANTICONF ERROR --------------------------- Configuration failed because poppler-cpp was not found.

Sorry if this is obvious, but my S skills aren't great and I haven't been able to find it documented anywhere. I want to write a new function for use with lme objects; the function will simply calculate an ICC (aka "rho") for each level of a mixed-effects model. What I need for this is pretty simple: (c(var1..varn, residual)) / sum(c(var1..varn, residual)) where var1..varn

Javier Muchas gracias por su respuesta Aunque no está funcionando, pues si ejecuto: EncDTE1<- t.EncDTE1[ !is.na(t.EncDTE1$Var1),] obtengo Var1, Var2, Var3,...Varn con datos "texto", NA, NA....NA Pero al ejecutar EncDTE1<- t.EncDTE1[ !is.na(t.EncDTE1$Var2),] obtengo Var1, Var2, Var3,...Varn con datos NA,"texto", NA....NA Estoy tratando de dar la vuelta con el loop

Hi everyone, What is wrong in below asterisk application?

I am taking my first steps in textual analysis with R. I have pdf files consisting of company reports for several years (1 file corresponds to 1 company and 1 year). My idea is to start by transforming all my pdf files into txt files for further treatment and analysis (this will allow me to group the files by company or by year, depending on the future analysis to be performed). I do not have

I want to draw a profile plot of each condition c1 to c100, which rows in above matrix and each line representing a row should be uniquely colored according to the group(1 to 10). I think this is simple task

Hi, we're using dovecot2.0 since August and very happy with it. Just recently Thunderbird users reported problems when renaming folders, and it seems that RFC 2060 (sec. 6.3.5) requires children of a renamed folder to be renamed, too. This however does not happen: Talking IMAP I get: * LIST (\HasChildren) "." "INBOX.NNN1" * LIST (\HasNoChildren) "."

Greetings again. I'm still trying to coerce a pile of data into a frequency table format. I've managed to do so using perl, so I now have a tab-delimited file that contains the contingency table I'm trying to use: Group var1 var2 ... varn B 42 11 3 C 44 1 12 ... X 12 0 19 I can read the table in using read.table(), but I end

Dear all, I am trying to find a suitable R-function for parametric proportional hazard regressions. The package survival contains the coxph() function which performs a Cox regression which leaves the base hazard unspecified, i.e. it is a semi-parametric method. The package Design contains the function pphsm() which is good for parametric proportional hazard regressions when the underlying base
