Dear all, Is there a less cumbersome way to rename a column by name (as opposed to index) than -- names( X)[ names[ X] == "bob"]<-"sue" ? A semi-related question: how does one get the index of a column by name, something along the lines of col.index( X, "sue") ?

Greetings, Q #1 ------ How does one combine data frames by row ... no cleverness a la merge(), just add rows. For example, given A with 20 rows and B with 30 rows, I want C = combine( A, B) having 50 rows. Columns having matching names should be filled from both (all) sources with suitable coercion, unmatched would get NA in rows whose source does not have that column. Q #2 ------ Given

Dear all -- I have a data frame containing data related to heat gain through windows. The general form is ... Key ProfA IAC <many other numeric columns> AAA 0 .7 AAA 10 .6 AAA 0 .66 AAA 20 .45 (more AAA rows) (then AAB rows) 'Key' identifies the physical configuration ... rows with a given Key contain data for same window under various

Dear all -- I want to compute weighted.mean() for grouped rows. Data frame extract is just below. For each Key, I want the mean of IAC weighted by Wt. DP0[1:20,] Key IAC Wt 2 C3-PD030020050.PD030020050.3.12.3.0 0.765 0.8590000 3 C3-PD030020050.PD030020050.3.12.3.0 0.764 0.8449651 4 C3-PD030020050.PD030020050.3.12.3.0

Dear R-ers, My aggregation saga continues. Using the following sequence, I can calculate any statistic for row groups and merge the result back to all associated rows ... > WM = by( D60, D60[ "KeyProfA"], FUN=function(x) weighted.mean( x$IAC, x$Wt)) > D60$IAC.WM = as.numeric( WM[ D60$KeyProfA]) > class( WM) [1] "by" Questions ... 1) Is this a reasonable way

Dear R-people ... I'm a new user. I can't get predict.lm() to produce predictions for new independent data. There are some messages in archived help about this problem, but I still don't see my error after reviewing those. I understand that the new independent data must have the same name(s) as used when the model was made. In the example below, predict.lm produces the

Hi, I'm a complete linux newbie, let alone wine, easy-peasy and netbooks. Having said that, I'm looking at buying the eee pc 701 sd and putting easy-peasy on it. However the reason I need a netbook is to run a cricket scoring program that is only available in windows. I didn't want to fork out for the netbook until I knew the cricket software will run, so I tried the following: 1.

Hi, I noticed there is an "-inplace" option on rsync web site's man page. So this seems to mean "copy then move" is the default behavior. Has this been the default all the time? I am running a pretty old version, see below, and I need to have the "copy then move" feature to ensure partial files are not accessed while they are being updated. [qt_prod@cflxqs55p

Is there a limit to the number of columns that a data.frame can have? For example, can I read.csv() a file that has 1000 columns and 10,000 rows, will it break or is it limited by available memory. ...................................................................................

Hi John, I've forwarded your info to the nut development list, and to Carlos who's in charge of the megatec driver. This one, which is only available in the subversion development tree, and soon in 2.0.4, will replace the fentonups driver. So you're encouraged to test it and report back.

I sent the message below to r-sig-mac yesterday, but having no reply I decided to explore a bit myself and found that editing: /Library/Frameworks/R.framework/Versions/2.3/Resources/share/make/ shlib.mk yzzy: diff shlib.mk shlib.mk~ 3c3 < include $(R_HOME)/etc/Makeconf --- > include $(R_HOME)/etc${R_ARCH}/Makeconf restored the functionality of R CMD INSTALL. Is this a known issue?

I have a new system which includes a Plextor PX-740a DVD+-R/RW CD-R/RW drive attached to an Asus A8V-MX motherboard. When I try to use burncd to burn a cd, it writes all of the data, says "fixating CD, please wait.." and then reports burncd: ioctl(CDRIOCFIXATE): Input/output error Oddly enough, the CD seems to be usable. I can successfully burn the same file if I use cdrecord. The
