Hello R users, Good day!! I was wondering if there is a way in R to read in a particular column from a tab-delimited file, edit it and write it back into the file with all other columns intact. When I say edit I mean just replacing all the values in that column. I know to read a particular column from a file using colClasses option in read.delim() function. Is there any such option to write out

Hello, All! How might one accomplish this using the by() function? m1 is a data frame. # populate column "m1$major_allele" for ( i in 1:length(m1$major_allele)) { if ( m1$Freq1[i] == m1$MAF[i]){ m1$major_allele[i] = m1$Al1[i] } else{ m1$major_allele[i] = m1$Al2[i] } } Jim [[alternative HTML version deleted]]

Hi All, I am trying to import a .sas7bdat file into R.

Dear All, It might be a simple question. But I could not find the answer from function “prcomp” or “princomp”. Does anyone know what are the codes to get coefficient and scores of Principal component analysis in R? Your reply will be appreciated! Best Zunqiu [[alternative HTML version deleted]]

Hi, I suffered an oss crash where my oss server had a cpu fault. I have it running again, but I am trying to decommission it. I am migrating the data off of it onto other ost''s using the lfs find command with lfs_migrate. It''s been nearly 36 hours and about 2 terabytes have been moved. This means I am about halfway. Is this a decent rate? Here are the particulars, which

Greetings, Last April, in this discussion... http://www.opensolaris.org/jive/thread.jspa?messageID=143517 ...we never found out how (or if) the Sun 6120 (T4) array can be configured to ignore cache flush (sync-cache) requests from hosts. We''re about to reconfigure a 6120 here for use with ZFS (S10U4), and the evil tuneable zfs_nocacheflush is not going to serve us well (there is a ZFS

Greetings, We''re trying out a new JBOD here. Multipath (mpxio) is not working, and we could use some feedback and/or troubleshooting advice. The OS is oi151a7, running on an existing server with a 54TB pool of internal drives. I believe the server hardware is not relevant to the JBOD issue, although the internal drives do appear to the OS with multipath device names (despite the fact

Hallo, I modified a code given by Andrija, a contributor in the list  to achieve two objectives: create 1000 samples from a list of 207 samples with each of the samples cointaining 20 good and 20 bad.

Hi All, I have a 1000x1000000 matrix. The calculation I would like to do is actually very simple: for each row, calculate the frequency of a given pattern. For example, a toy dataset is as follows. Col1 Col2 Col3 Col4 01 02 02 00 => Freq of ?02? is 0.5 02 02 02 01 => Freq of ?02? is 0.75 00 02 01 01 ? My code is quite simple as the following to find the pattern ?02?.

Is there an "easy" way to plot a "color key" next to a color image (with image() in graphics package)? The color key should also include a numerical scale, so that the colors can be cross-referenced with image intensity values. I see that levelplot has a facility for color keys, but with image it seems less straightforward, i.e. generating a color key is not an option in

Hello, How do you print a variable name in a for loop?
