Hello everybody, I am beginning with loops and functions and would be glad to have help in the following question: If i have a dataframe like this Site Prof H 1 1 24 1 1 16 1 1 67 1 2 23 1 2 56 1 2 45 2 1 67 2 1 46 And I would like to create a new column that subtracts the minimum of H from H, but for S1 and P1 only

I am finding complex analyses easier than some elementary operations in R. In particular I want to do some low level exploratory data analyses with data in a data frame but cannot find commands to easily insert, remove (delete), rename, and re-order (arbitrarily, not sort) columns. I see that the micEcon package has an insertCol command, but that is for matrices, not data frames. I have looked

I'm coming out with all the classic problems today ;-) Can anyone tell me how to change the column names of an already existing data frame? I've read the docs for ?data.frame and ?as.data.frame but can't figure it out. I want to make a new data.frame from some of the columns of an existing data.frame, but when I do that, the new data.frame columns have the same names as the old

Hello -- Is there any R function that implements Wrapper Subset Selection method? I am using 'leaps' package, and I do not know if 'leaps' works better than Wrapper. Thanks, Vu

These two patches affect the interrupt injection logic for AMD-V (only). These patches fix issues with Windows HVM guests during boot menu screen: 1) the timer countdown is no longer very slow 2) kbd response is now no longer slow or non-existent We have also seen an occasional "dma lost interrupt"/expiry errors, and these patches seem to help with these, especially with SUSE10 HVM

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 What is the standard procedure for making edits of smb.conf take hold? For example, what I'm seeing is a share that has given R/W access to a user named Tom, when I change Tom to read only, he is still able to write to that share until I stop Samba and restart it. The documentation seems to refer to a 1 minute reread of smb.conf, but I don't

Hi all, I just pushed out SYSLINUX 3.71-pre15. This version officially begins the release candidate stage of SYSLINUX 3.71. To be honest, I'm a bit baffled that the numbers got that high for what has always been intended as a maintenance/bugfix release, but those 15 prereleases only correspond to 55 commits total, so I guess it's really not that much. -hpa

Dear all, Me and the Garbage Collector doesn't understand each other... I'm on R-1.0.1 (I have requested an upgrade to the right local people), an osf1 system with an alphaev6 CPU. I have fair amounts of memory to use, but it seems to be used up pretty fast nevertheless. I'm now trying to see what the garbage collector does, I have inserted a gc(v=T) call at a spot in my code. I

Hi Folks, I''ve got a 3.9 Tb zpool, and it is casing kernel panics on my Solaris 10 280r (SPARC) server. The message I get on panic is this: panic[cpu1]/thread=2a100a95cc0: zfs: freeing free segment (offset=423713792 size=1024) This seems to come about when the zpool is being used or being scrubbed - about twice a day at the moment. After the reboot, the scrub seems to have

I want to take the first row of each unique ID value from a data frame.
