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") ?

Hello, I would like to create a subscriptable collection (presumably a list) of lm() models. I have a data frame DX containing 6 groups of data. The general idea is (NOT RUN) ... for (i in 1:6) { DXS = subset( DX, <whatever>); LMX[ i] = lm( <formula>, data = DXS); } Now access model results by subscript ... e.g. coefficients( LMX[ 2]). Or would it be [[ 2]]? I

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 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

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

Hi, We have a problem with Syslinux 2.07 and APM on an SMP system. When either network booting with pxelinux.0 or CDROM booting with isolinux we get a kernel error message: Jan 7 09:59:51 ddcserver1 kernel: kernel BUG at apm.c:1756!

Trying to run EVE Online through wine on my Asus EEEPC with a special flavor of Ubuntu called Easy Peasy built for netbooks. I run the app after doing all the necessary installation procedures and once the game goes full screen, I get sound just fine but the screen goes black and eventually freezes the computer entirely. I ran wine through terminal and got these errors: Code:

Can anyone here help me out with a client side Outlook issue? I know outlook is a horrible imap client :( We intermittently have a problem where mail gets "stuck" in Outlook users' outboxes. Might have anything to do with dovecot? Is there anyway I can troubleshoot this server side? Are there any settings I can tweak? We have a new and an old dovecot server (see below) and both

Dear R helpers,   Following is a R script I am using to run the Fast Fourier Transform. The csv files has 10 columns with titles m1, m2, m3 .....m10.     When I use the following commands, I am getting the required results. The probelm is if there are 100 columns, it is not wise to define 100 commands as fk <- ONS$mk and so on. Thus, I need some guidance to write the loop for the STEP A and

Hi, I got a small problem on how to define the vector index without manually inspect the vector. example: y=c(2,3,5,2,4,6,8,3,6,2,5) #I have ten set of this kind of vectors (with different values but same length) that I would also like to run the routine below #say; v=the first index in y where the value is larger than 4, in this case index 3, value 5 #what I would like to do is take y[1:v]

I manage a set of CentOS operations workstations which are all clones of each other (3 "live" and 1 "spare" kept powered down); each has a single drive with four partitions (/boot, /, /home, swap). I've already set up cron'd rsync jobs to copy the operations accounts between the workstations on a daily basis, so that when one fails, it is a simple, quick process to swap

hi i'm using the system with pIII,intel 815 chipset with PXE enabled bios...and 3com NIC.. on the server side i'm using pxelinux.0 as boot loader,dhcp server and tftp server.. when i boots the system dhcp reply is proper .. i captured the packets.. so it shows that it ask for pxelinux.cfg/c0a80115 file then the client get rebooted automatically... it doesn't send any packet asking for

Greetings I'm attempting to insert missing data on the smallest size class of cave cricket instars into a data frame. The data involve censusing photoplots (plots) of roosting cave crickets in which we discern in four instars or size classes. I need to insert data on size class one into a data frame that already has data on size classes two through four. The data can be merged by their
