Hi all, can the glm package be used to estimate a logit model to panel data? I am asking this because stata has a standard logit model and then an xtlogit for longitudinal data. Is there something similar in R? Thank you jcm [[alternative HTML version deleted]]

i have a loop which looks likes this: > data.info <- rbind(data.info, cbind(station.id, year, date, > max.discharge)) + y <- split(data.info, data.info[station.id]) + for (i in names(y)) {write.csv(y[[i]], file=paste(i, ".csv", sep=","))} i am wondering, where the file (which i am about to write in .csv format) will be saved? i looked at ?write.csv and

Hello helpers, This is probably quite simple, but I'm stuck. I want to create a summary statistics table with frequencies and summary statistics for a large number of variables. The problem here is that (1) there are two different classes of categories (sex, type of substance abuse and type of treatent) which overlap, (2) the data for different variables should be presented in different

Dear R-helpers, I have a data frame with 3 variables, each record is a unique combination of the three variables. I would like to count the number of unique values of v3 in each v1, and save it as a new variable v4 in the same data frame. e.g. df1 [v1] [v2] [v3] [1,] "a" "C" "1" [2,] "b" "C" "2" [3,] "c" "B"

i use the GUI version of R on OS X. I launch it by double-clicking on the R icon. The process always starts in my home directory which means that the only .RData file that is ever read in is the one in my home directory. I would instead like to have different R sessions saved in different directories, but I can't figure out how to do this. A workaround is to use the shell version of R and

I am trying to update the packages that I have installed but I get the following warning messages: package 'tseries' successfully unpacked and MD5 sums checked Warning: cannot remove prior installation of package 'tseries' bundle 'forecasting' successfully unpacked and MD5 sums checked Warning: cannot remove prior installation of package 'forecast' What does that

Hi, I have a simple linear regression for which I want to obtain HAC corrected standard errors, since I have significant serial/auto correlation in my residuals, and also potential heteroskedasticity. Would anyone be able to direct me to the function that implements this in R? It's a basic question and I'm sure I'm missing something obvious here. I looked up this post:

The incorrect result incurs when the file path contains Chinese character. It seems that dirname/basename action on unit of byte instead of char, so the result in the following example is half of what is expected. > g<-"d:\\$BG!2L4^M-CfJ8(B\\$BG!2L4^M-CfJ8(B.txt" > dirname(g) [1] "d:/$BG!2L4^(B" > basename(g) [1] "$BG!2L4^M-(B" -- HUANG Ronggui,

Dear all, I am trying to install RSQLite package since I want to install "sqldf", and I used >> install.packages("RSQLite") first, which gave Error message as below: make: *** [RS-DBI.o] Error 1 chmod: cannot access `/usr/lib/R/library/RSQLite/libs/*': No such file or directory ERROR: compilation failed for package 'RSQLite' ** Removing

Dear All, I use R to conduct multilevel modeling. However, I have a problem about the interpretation of random effect. Unlike the variables in fixed effects, the variables in random effects have not shown the p-value, so I don't know whether they are significant or not? I want to obtain this figure to make the decision. Thanks a lot! Below is the syntax and output of my program:

Dear All, I distributed the HTML style one year ago ( http://www.biosino.org/pages/newhtm/r/schtml and http://www.biosino.org/pages/newhtm/r/tchtml). Now I polished it, and rewrote it with Latex. You can download it from the URL: http://www.biosino.org/R/R-doc/ ( http://www.biosino.org/R/R-doc/files/R-intro_cn.pdf). Wish it will be useful for Chinese R users. Any

Hi, I am wondering if some experienced users would help put the ready-to-run code of the examples in the manuals. It would help new users learn R faster by putting all the examples in an ready-to-run R script file. Can somebody help do so sometime and post the code along with the pdf manuals? http://cran.r-project.org/manuals.html Regards, Peng

Dear list, I have been working on a report with around 60 images in it, and everything has been fine, until now. I find that the image output that is produced by odfWeave produces images that are NOT readable by OpenOffice or NeoOffice. I get empty boxes with Read-Error written in them. While generating the file using odfWeave, I can see them being generated on the screen, and they all seem fine.

R-helpers: Are there any ways to auto-generate R-friendly (e.g. will pass a compilation check) .Rd files given a set of .R code? How about GUIs that help properly format the .Rd files? Thanks! I want a basic set of .Rd files that I can update as I go, but as with most things my documentation typically lags behind my coding by a few days. --j -- Jonathan A. Greenberg, PhD Assistant Project

Quick informal poll: what is everyone's favorite text editor for working with R? I'd like to hear from people who are using editors that have some level of direct R interface (e.g. Tinn-R, Komodo+SciViews). Thanks! --j -- Jonathan A.
