similar to: switch() vs eval() for choosing pre-existing alternatives?

Hi, Does anyone know if the alternatives in the 'switch' function can be specified as strings containing spaces?  Neither of the two approaches below works. switch(expr, "Choice 1"="My first choice", "Choice 2"="My 2nd choice", "Choice 3"="My 3rd choice") x <- c("Choice 1", "Choice 2", "Choice

Hello, After reading help file, various threads on this board, and other online tutorials, I've attempted to use gsub (using Perl-like syntax) to change a currency string into something that can be converted to numeric type using only one regular expression.  Can anybody point out my error?  Note that >  x <- "\"$ 1,200,300,400.50\"" Tried the following in an

Hello, I'm trying to figure out how to find the index of the second occurrence of "/" in a string (which happens to represent a date) within a data frame column. I've used the following code successfully to find the first instance of "/". dframe <- data.frame(date=c("5/14/2011", "4/7/2011")) dframe$x1 <- regexpr("/", dframe[, 1])

Hi, Would anyone have any idea as to why I would obtain completely different results when subsetting using the subset function vs bracket notation? I have a data frame with 65 variables and 4382 rows. When I use execute the following subset command I get the correct results (125 rows) > subset(df, Renewal==TRUE, 1:2)   However, I tried to obtain the same results with bracket notation as

Hi, I have a data frame with column names "1", "2", "3", ... and I'd like to extract a subset based on the values in the first column. None of the methods I tried worked (below). x <- subset(dframe, 1 = = "My Text") x <- subset(dframe, "1" = = "My Text") x <- subset(dframe, names(dframe)[1] = = "My Text") Q

Hello, I'm wondering if the 'mosaic' plot of the vcd package (or any other function for that matter) can be used with a continuous variable that should be represented via various categorical variables.  All the documentation I've read lead me to believe that it only works with counts of categories. Alternatively, I've thought of first creating a contingency table where the

Hello, Is there a way to set the maximum width of character columns when printing a data frame? I've looked into print(), format(), and options() and have been unsuccessful. For example, I'd like to achieve the results below without having to modify the data itself. > x <- data.frame(c1=rnorm(5), c2="ABCDEFGHIJKLMNOPQRSTUVWXYZ") > x c1 c2 1

Dear List, While trying to define a customised CITATION file for a package, following R-exts, I realised that if I use only one 'citEntry' I got both a text description and a BibTex entry for the package, as for the 'nlme' package: -------------------------- citation('nlme') To cite package 'nlme' in publications use: Jose Pinheiro, Douglas Bates, Saikat

I thought I wanted to set up my Solaris file-server as domain controller for my small home network, but the more I look at it the less I'm sure. Plus I'm having trouble doing it :-). I do plan to put my primary files (and other people's) on the server, for better safety (mirrored disks, and ZFS) and backup. I certainly want the logon transactions over the network to be encrypted,

Dear R users, I have been trying to use RQuantLib in the 2.12.2 R version. I downloaded the .zip file from <http://sourceforge.net/projects/quantlib/files/QuantLib/> http://sourceforge.net/projects/quantlib/files/QuantLib/ which didn't work, so I I downloaded the package source from <http://sourceforge.net/projects/quantlib/files/QuantLib/1.0.1/>

Thank you very much Christophe by your advice. However, my situation was the opposite to yours, because I'm behind a proxy but my sudo account couldn't see it, and when looked for the proxy configuration of the sudo account with : $ sudo printenv | grep proxy the result was empty. Finally, thanks to all the advice received in this thread, I could fix the problem by editing the

Hi, I want to select a subsample from my data, choosing one record from each group. I know how to do this with a for. For example: lets say I have the data: A=cbind(rnorm(100),runif(100),(rep(c(1,2,3,4,5),20))) Where the third column is the group variable. Then what I want is to select 5 observations. Each one taken randomly from each group. INDEX =NULL i=1 for(index_g in
