similar to: How to delete rows from dataframe that sum to zero

I have a data frame with three columns, one coded as a factor. I would like to separate my data out into separate data frames according to the factor level. Below is a simple example to illustrate. I can get R to return the data in the correct format but cannot work out how to get separate data frames. I am a newcommer to programming in R so am not sure what I am missing! Thanks, Emily

I've got a win98 laptop and a linux box. On my linux box, I smbmount a directory from the laptop. Alas, win98 boxes crash a lot, and I move the laptop a lot... to and from work. If the laptop crashes or if I move it with a shared directory mounted on my linux box, that mount gets "Stuck".... it's present in /etc/mtab but when I cd to it and do an ls it says: 243 emily ~>ls

rsync does not sync the timestamp on symlink (Solaris 8). It is probablly due to the limitation of Unix implementation of symlink, but I would like to know why rsync/Unix does not do this, and what we can do about it. Is the conclusion that "rsync syncs everything except the timestamp on symlink"? Why do I need timestamp on symlink? Supposed something stopped working because something

Hello. I apologize if there is a simple answer to this question, but I haven't been able to figure it out. Our people use various clients (pine 4.50 with maildir patch, eudora, messenger, outlook, squirrelmail), and all of them work with courier-imap. But I've become very interested in dovecot after reading about it, so I'm trying it out on another server. The results are mixed.

I'm running Samba v2.2.5 with ACL support for xfs from SGI on modified Redhat Linux 6.2 running Linux kernel 2.4.19 with xfs filesystem support. Samba is running in domain mode and my PDC is an NT 4.0 SP6 server. I'm using a Win2K Professional (a member of the domain) to test things out. I have no problem setting ACL to a file from the Win2K PC. For example, I allow only Read (RX)

Hi I've got a samba PDC (samba 2.2.3a, RH 7.2, kernel 2.4.17, client is WinXP pro). I have a question about the homedrives-part in smb.conf. Are the homedrive shares set up to allow access exclusively to the appropriate user and no-one else ? My smb.conf looks like that [homes] comment = Home Directories browseable = no writable = yes valid users = %S create mode = 0664

Hi everyone: I need to count the number of banks of each firm in my data. The firm is identified by the fiscal number.

Hello, I’m reaching out because our online radio station (sites.up.edu/kdup/) has stopped streaming in the last week - the website itself works fine but when anyone attempts to listen to the live music stream they receive a message that says “cannot connect to the server “icecast.up.edu.” Do we need to update the server, or is this a problem that someone else can take care of? Let me know if I

Hello, all I am building a R package using Fortran source code. The Fortran code is a subroutine. I can use "R CMD SHLIB bar.f -o bar.o" to create the shared library. For the R package, I put the fortran file in the src/ and I use R code as follows: ".First.lib"<-function(libname,pkgname){library.dynam("barpkg",pkgname,libname)} barfun<-function(n,x){

I thought replacing the spaces following instances of +++,++,+,- with "\n" and then reading with scan should succeed. Like Ivan Krylov I was fairly sure that you meant the minus sign to be "-" rather than "?", but perhaps your were using MS Word as an editor which is inconsistent with effective use of R. If so, learn to use a proper programming editor, and in any case

The Peabody Research Institute at Vanderbilt University is looking for a Consultant who can develop an R package for robust standard error calculations in meta-regression models. The consultant will be expected to translate an already developed R function into a more fully functional R package with additional analysis and output options. The ideal candidate will be an experienced R programmer who

Good day, I'm ran aov () and lme() on a split-plot using a 64-bit machine. For aov() I don't see the values for ErrorA, F-value and p-value in the output. For lme(), output is different from results from a 32-bit. Please see codes used and corresponding output. Is my code wrong and/or not sufficient or is this a compatibility issue? ************** model1<-aov(Y~Main*Sub +

Hi, please can you help me. When I add a legend to a boxplot it appears inside the plot area, how do you get it into the margins? I have already changed the parameters so there is space for it on the margin on the right hand side of the graph. Thanks, Emily [[alternative HTML version deleted]]

I'm trying to figure out if it's possible to use a character string as an equation, e.g: eqn1string <- "x^2 + x + 5" Then I want to tell R: 1) that eqn1string is actually an equation (even though it was stored as a character string), and 2) to apply the equation to a specified value of x (e.g. given x <- 6, what is the result of the equation). Thanks in advance for any
