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 s...

Hello llvm-dev! My colleages and I are currently evaluating llvm's suitability as a JIT compiler interfacing with a precise, relocating garbage collector. While we couldn't find code or writeups that deal with the issues specific to this design goal, it is entirely possible that we may have missed something; we would...

Hi I discovered a similar problem early this week and a colleage on irc was told it was a copy and paste error. in man syslogd, the following can be found: Sucker rod def. -- 3/4, 7/8 or 1in. hardened steel rod, male threaded on each end. Primary use in the oil industry in Western North Dakota and other locations to pump 'suck' oil from...

Hi, I have just taken over the administration of our Samba Fileserver. Unfortantly, my colleage has not done his homework and sadly forgot keep the Samba version up-to-date. So, the first step for me would be to update from our current version 3.0.23c (SuSe rpms) to the most recent. Now I worry about some changes that could cause problems with my current configuration file. As I can not shutd...

...n some prior releases due to the use of both unique(times) and table(times); I fixed it by rounding to 15 digits per the manual page for as.character. Yes, I should ferret out all the usages instead, but this was fast and it cured the user's problem. The bug is back! A data set from a local colleage triggers it. I can send the rda file to anyone who wishes. The current code has digits <- floor((.Machine$double.digits) * logb(.Machine$double.base,10)) #base 10 digits Y[,1] <- signif(Y[,1], digits) which gives 15 digits; should I subtract one more?...

...;s friends (used to be a friendships table, but when that table grew to tens of millions of records, we refactored it to a User''s attribute). The User model in our app is saved very frenquently, and many users have more than 1 handred friends, so the friend_ids may has 1kB long. Some of my colleages opposed to use serialized friend_ids, and suggested to used a comma separated string instead because saving 1kB each time would have performance issue.

I could for example no longer start ADUC, some users could not logon or map drives, etc, etc. >From samba's point of view everything was still running, replication was happening, etc, etc. No idea where to start looking. Until my colleage told me about this moving of disabled accounts from CN=Users into OU=disabled. Turned out he had also moved the disabled account "krbtgt", and this had caused our network to fall apart. Luckily his ADUC window was still open and functional, so we could move this account back into CN=Use...

...ted entry another way. By the way, I also noticed what is probably an accidental checkin in src/lib-storage/index/maildir/maildir-storage.c:maildir_get_control_path(), where it tries to migrate control files from the default location to the configured location. I think Timo wrote that patch for my colleage Cor, and then accidentily checked it in with: ---------------------------- revision 1.100 date: 2005-06-09 14:31:43 +0000; author: cras; state: Exp; lines: +22 -4 Replaced ':' and ',' character usages with #defines, so they can be changed easily if needed. The patch is 'bro...

Colleages I am running R 2.1.0 on a Mac (same problem occurs in Linux). In some situations, I have mixed text/numeric data that is stored as characters in a matrix. If I convert this matrix to a dataframe, the numeric data becomes factors, not what I intend. TEXT <- paste("Text&quo...

...lleagues have achieved when running the same exact code on the same exact data. The error message that populates my R output window is as follows: "Error in sample(length(x), size, replace, prob) : NA in probability vector". I do not understand why I receive this error message, whereas my colleages do not. Any guidance/advice would we extremely helpful! Thank You!

Message I recieved from a work colleage.... Wonder if anyone can help the guy? --------FORWARDED MESSAGE---------------------- I finally ditched my freebsd and put centos on my box. Trouble is I can''t figure out how to get it to automount my USB and firewire (ipod) bits. Any ideas? Googling has left me a bit frustrated. No...

...accination makes expression go down. In both the vaccinated and unvaccinated groups, infection makes expression go down, but it goes down further in unvaccinated than it does in vaccinated. So from a statistical point of view, I can see exactly why the interaction term is significant, but what my colleage wants to know is that WITHIN the vaccinated group, does infection decrease expression significantly? And within the unvaccinated group, does infection decrease expression significantly? Etc etc etc Can I get this information from the output of the ANOVA, or do I carry out a separate test on e.g....

I did some serach around. It seems that ROC curve computation is not supported on R. Anyone has some leads? Thanks. Jason ===== Jason G.

Dear colleages in R, I have earlier been working with R in Linux, where reading in a table containing Scandinavian letters ("?", "?", and "?") in the header as part of variable names has not caused any problem whatsoever. However, when trying to do the same in R running on new M...

Hi I am having some problems running a covariate analysis with my colleage using R with the NonMem program we are using for a graduate school project. R and NonMem run fine without adding in the covariates, but the program is giving us a problem when the covariate analysis is added. We think the problem is with the R code to run the covariate data analysis. We have the co...

Dear All, This is not strictly R related (though I would implement the solution in R; besides, being this list so helpful for these kinds of stats questions...). I got a "strange" request from a colleage. He has a bunch (approx. 25000) subjects that belong to one of 12 possible classes. In addition, there are 8 covariates (factors) that can take as values either "absence" or "presence". Some of the subjects only have one covariate with value "presence" (the other...

...oss-validated improvement for the first split isn't much (R^2 < .04). Now to the larger debate. I do not find trees as useless as Frank (does anyone). I like to use them for initial data exploration, in the same fashion as a scatterplot. But I fight the same battle that he does with some colleages and customers: they are so very easy to interpret that the results are often severely over-interpreted, sometimes to the point that the tree did more harm than good. All forward stepwise procedures are unstable. Particularly with rich data sets, such as I see each day in the medical field, there...
