Uncorrelated random vectors
Hello, is it possible to create two uncorrelated random vectors for a given distribution. In fact, I would like to have something like the function "rnorm" or "rlogis" with the extra property that they are uncorrelated. Thanks for your help, Luba [[alternative HTML version deleted]]

error: compiling R package
Hello, I tried to build an own R package on Windows XP but get an error which I can't solve. I called my package "pack". It works to creat the file "pack" with package.skeleton(). But when I try to compile it with Rcmd build --binary pack I obtain the following error: IO::Seekable::seek missing at C:/R/R-2.9.0/share/perl/FileHandle.pm line 59. Compilation failed in

re gression trees: mean square vs. absolute errors
Hi, I am working with CART regression now to predict a probability; the response is binary. Could anyone tell me in which cases it is better to use mean square error for splitting nodes and when mean absolute error should be preferred. I am now using the default (MSE) version and I can see that the obtained optimal tree is very different from the tree with the least mean absolute error. Thanks in

CCF for hourly time series?
Hello, I have a dataframe containing various time series (not time series objects though!)with hourly time steps. I?d like to perform ccf for I need to know the correlation factors for different lags. Here is an example: x<-as.POSIXct(c("2008-12-25 16:00:00", "2008-12-25 17:00:00", "2008-12-25 18:00:00", "2008-12-25 19:00:00", "2008-12-25

arrays of arrays
Hi All, I want to have an array/ matrix that looks this x<- 0 0 1 1 1 3 5 4 4 7 -1 8 9 10 6 I hope this makes sense. So basically if I want x[1,3] it will access 0 and similarly x[4,2], -1.

comma separated format
Hi All, I'm trying to create labels to plot such that it doesn't show up as scientific notation. So for example how do I get R to show 1e06 as $1,000,000. I was wondering if there was a single function which allows you to do that, the same way that as.Date() allows you to show in date format on a plot.

switching only axis off in plot
Hi R, In the following code my x-axis is formatted in month format. Which Im happy with. The y-axis is what I want to re-format with something else. My question is, is it possible just to switch off the xaxis in plot function (see below). If not how do you get the months to show up as FEB-YYYY, MAR-YYYY and so on, so I could fit a label on x-axis. Thanks, Sachin p.s. sorry about corporate

drilling down data on charts
Hey all, Suppose a=b^2 for starters. I want to be able to create a graph that displays a initially and if i was to click on 'a' to show 'b' on the chart itself. Does anyone know if this is possible in R? Also as an extension (not necessary as yet) to output the above into a 'html' file.

Hi all, Just following on from a previous thread (for loop). Is there a parallel 'for' loop like matlab (parfor maybe?). I know there was a Nvidia GPU version for blas somewhere. But is there a CPU or a GPU version of the for loop? Thanks, Sachin p.s. sorry about the corporate notice below: cant get rid of it.

Running R on a server
Hi All, I am trying to run R scripts on a server rather than my own machine. The biggest reason being that the data can be 3GB+; more than my RAM can handle. Anyway is there a way to do this. I am trying to find a SAS alternative. In SAS you can do (keyword) rsubmit; and get things running remotely on a server. Is there something similar on R. Couldn't find a comprehensive answer online.

plot options including formatting axes
Hi All, Currently my plot shows the y-axis in scientific notation (1e07 and so on). I want to be able to display this in dollars such that it shows $10,000,000 (including the commas). How do I do this. Also with the xlabel and ylabel. I've specified: 'title('Cash vs Time',xlab='Period',ylab=''); Im hoping that this will also not display anything on the y-axis.
