Hi, I have a medium-sized (19MB) CSV file that I'd like to read into R. The read.csv() function seems to be a bit inefficient to deal with it, and I remember that using scan() with "what" options is better. However I'm unable to understand how to use it. The first few lines of the data look like:

Hi, Suppose I use the following codes to read in a data set. ############################################### > rating <- scan("../Data/Rating.csv", + what = list( + usage = "", + mileage = 0, + sex = "", + excess = "", + ncd = "", +

Hi Gunter, I think this problem started happening when I upgraded from Debian Wheezy to Debian Jessie. If nothing looks amiss in my code, it probably is a sound driver problem. But since it works 100% of the time in ogg123, I feel I must have missed some corner case. My audio driver is almost always active. I usually have my music player going in the background when I do my testing. The problem

Hi Gunter, I've solved the sound glitch. Since it was hard to reproduce, it took me a while, but I eventually figured it out. What I needed to do was fill the buffer with more data before handing it off to ao_play. It requires lots of bookkeeping, pointer arithmetic, and a sufficiently large buffer. First, the bigger buffer. I just pulled this code from ogg123: #define PRIMAGIC

Hi, I am trying to change a SAS macro to R. here is my code.

Hi all I have another GLIM question. I have been using R as well as Genstat (version 6) in order to fit GLIM models to the data (displayed below). The same models are fitted but the answers supplied by the two packages are not the same. Why? Can anyone help? A discription of the data and the type of model/s fitted can be found below.

Dear R, I've got a data frame with children examined multiple times and at various ages. I'm trying to find the first age at which another variable (LDL-Cholesterol) is >= 130 mg/dL; for some children, this may never happen. I can do this with transformBy and ddply, but with 10,000 different children, these functions take some time on my PCs - is there a faster way to do this in R?

Dear r-help subscribers, A couple of weeks ago I sent the following message to the r-help mail list. It hasn't generated any response, and I could really use some help on this. Anyone able to help? Thanks again, Roger Dungan >> I am working on some survival analysis of some interval censored failure time data in R. I have done similar analysis before using PROC LIFEREG in SAS. In

Hi, I am trying to runn a age-period-cohort model, but here is what I am having problem with, hope you can help me! This is what I am trying to do: sumzero_a<-((A-min(A))/5+1) - mean((A-min(A))/5+1) where A is my age variable (numeric, the mid-point of a five-year age group), but I got the following error: Error in min(..., na.rm = na.rm) : invalid 'mode' of argument I am pretty

Hi, I am a newbie and I have installed Wine release 20000909 on a machine running Mandrake7.2 and win2000. The DefaultLoadOrder for the DLLs are builtin, so, native & elfdll. LD_LIBRARY_PATH and EXTRA_LD_LIBRARY_PATH points to the directory containing the lib*.so files. I encontered the following errors while running a place & route tool.

Dear r-help subscribers, I am working on some survival analysis of some interval censored failure time data in R. I have done similar analysis before using PROC LIFEREG in SAS. In that instance, a gamma survival function was the optimum parametric model for describing the survival and hazard functions. I would like to be able to use a gamma function in R, but apparently the survival package does

Hi, I want to build a system where 6 months old mail to be moved to archive server to keep my mailbox clean and fast. Is there any way to achieve the same using any pre-built binary shipped with dovecot ? Thanks and Regards Joy

Thanks for the help, however I don't think your suggestion applies in my case. On a fresh install of Samba 4.7.4 AD you cannot change a user password on a logged in PC through cntl-alt-del -> ChangePassword because the default MinAge is 1 days. I had to use the "samba-tool domain passwordsettings set --min-pwd-age=0" command to make the logged-on style of password change

I'm running Samba 2.0.0 on Solaris 2.5 and 2.6. I've had a report that a user on a Wincenter machine (NT4 + Windows Terminal Server + Citrix Metaframe + NCD stuff) dragged a Word document from his NT fileserver onto one of my Samba servers and the result was filled with zeros. We have been able to reproduce the problem from annother account on the Wincenter machine, but cannot make it

Case cohort function cch() is in survival package. In cch(), the prentice method is implemented like this: Prentice <- function(tenter, texit, cc, id, X, ntot,robust){ eps <- 0.00000001 cens <- as.numeric(cc>0) # Censorship indicators subcoh <- as.numeric(cc<2) # Subcohort indicators ## Calculate Prentice estimate ent2 <- tenter ent2[cc==2] <-
