Hi Folks, I'm running 32-bit R 2.14 in RStudio on my Win 7 x64 system with 8GB RAM. I'm getting memory problems as R wants to swallow more than the 4GB limit. I think I'm stuck at 4GB as I have to use 32-bit R for a number of packages (ODBC, etc). However, I doubt I really need to be using that much memory - I'm probably being very sloppy in my memory management, leaving lots

Hello, I have noticed that the memory usage inside an R session increases as more and more objects with unique names are created, even after they are removed.

Dear R-users, I have a dataset with categories and numbers. I would like to compute and add cumulative numbers to the dataset. I do not understand the structure of by(...) or tapply(...) output enough to handle it.

Hello, I am loading a DBF file into R via JGR and am having trouble creating small multiple histograms on a date variable. Hist() handles the variable correctly. But I've been unable to work with lattice or ggplot2 despite trying format() and as.POSIXct(). Dates are in the format "2010-05-15" and the grouping variable is categorical. I'd appreciate it if someone would provide an

Dear Community, I have been using two types of survival programs to analyse a data set. The first one is an R function called aftreg. The second one an STATA function called streg. Both of them include the same analyisis with a weibull distribution. Yet, results are very different. Shouldn't the results be the same? Kind regards, J -- View this message in context:

Just wanted to start a discussion on whether R could ship with more appropriate GC parameters.
