Hello, I would like to select cases using multiple logical operations (e.g. X or Y or Z) without having to repeat the dataframe$variable within the subscript. My working code (with a single logical operator) currently looks like this: dataframe$newvariable[data$oldvariable=="X"]<-"group1" I thought this next line of code might do what I wanted, but it doesn't:

Hi guys, I checked previous posts and I saw similar questions have been answered; they didn't help me solve my problem though. I am using R version 2.13.0 (2011-04-13), Platform: x86_64-pc-mingw32/x64 (64-bit) and I am having difficulties renaming variables. I tried with this command: names (oldvariable) <- 'new_variable' and now when I type in oldvariable the new name pops out

Hallo, I have got an existing data frame and want to add a new column. The existing data frame was created like this: > df <- rbind( c("Fred", "Mary", 4), c("Fred", "Mary", 7), + c("Fred", "Mary", 9), c("Barney", "Liz", 3), + c("Barney", "Liz", 5) ) > df

Hallo, I build a list by the following way: Lst = list(name="Fred", wife="Mary", no.children=3, cild.ages=c(4,7,9)) I know how I can extract the information one by one. But now I want to add a new entry which looks like name="Barney", wife="Liz", no.children=2, cild.ages=c(3,5) How can I add this information to Lst without overwriting the first entry?

I thought I had things figured out, but guess not. I have multi-user Quickbooks databases that functioned fine on a Novell server but are behaving badly on a Samba share. I have created a separate share for the Quickbook databases, users are running Win XP Pro, latest patches, and the Quickbooks application installed on the desktop. It is a multiuser version. Server is RedHat ES 3, Samba

Hi all, I am trying to call the R script/ R Program via my Shell Script. I need to pass a file to the R script as an argument. When I am trying to do that I am getting error and only first line of the file is being read. Can you tell me how should I do that so that it reads the entire file in a R object so that later I am able to process the matrix operation on that file. It is a tab delimited

Hi All, It is possible to make Opus/CELT a lossless coder if I allow a sufficiently high bit rate? We considered using FLAC, but FLAC's latency is well beyond the acceptable range.

Hi there, Can somebody please explain to me why Samba 3 requires 'oplocks = no' on shares for programs like Quickbooks to operate properly with multiple users, where Samba 2 didn't? Without this option, Quickbooks will complain about file corruption when a second user tries to open a file. This option, however, makes the particular share that the option is present in _very_ slow

Hey, I was using lme and proc mixed in SAS to run a empirical bayesian model. I used the same method for both lme and proc mixed (the default REML). I got very similar, but not identical results. I am just wondering if anyone knows what the differneces may be between proc mixed and lme. Any thoughts would be appreciated! Thanks, Liz

Hi, I would like to draw a graph as follows: A simplified example is that on the X axis are different countries, I have several temperature measurements taken from each country and would like to plot these linearly above each country. So one would imagine that cold countries would have lots of points at lower temperatures and the opposite for higher countries with a few outliers. I am not sure

Hi, We were wondering how we could make a stacked frequency diagram such as this one: http://msemac.redwoods.edu/~darnold/math15/liz.pdf We don't necessarily need the shaded "balls", other characters would be fine, such as stacks of x's. David
