There is a 'write.arlequin' function in the strataG package that will create an arlequin input file from a strataG gtypes object. You can create a gtypes object with sequence data read in from a FASTA file and stratifications described...

Roland, I think you were almost there with your first example. Howabout using: > x <- c("abcdef", "defabc", "qwerty") > y <- grep(pattern="abc", x=x) > z.char <- x[-y] > z.index <- (1:length(x))[-y] > > z.char [1] "qwerty" > z.index...

Thanks all for the responses. Running Rstudio from the command line does seem to work, but is clearly not the ideal solution. Nor is modifying the path to executable as I have these system calls embedded within a package which...

All, I'm trying to set up a function which calls the partialPlot function but am getting an error that I can't seem to solve. Here's a simplified version of the function and error... > pplot <- function(rf,pred...

R-help, I'm getting some unexpected behavior with subsetting a data frame (aircraft flight data) that I can't sort out. Here is a simplified version of my data frame and problem: > flight FlightID TailNo FlightDate HobbsTime FlightCost Date...

List gurus, I'm trying to code a Gompertz growth curve function as part of a larger project and have run across a problem due to my ignorance of environments. Some sample data and the function are as follows: growth...

R-users, I'm seeking any suggestions on optimizing some code for speed. Here's the setup: the code below is part of a larger chunk that is calculating Fst values across loci and alleles. This chunk is designed to...

Luke, Thanks for this point out. I started removing packages one-by-one in R v.3.3.1. Oddly enough, it went away after I removed the Matrix package. When I restarted R, the same version of Matrix (1...

Thanks Duncan! That's the perfect solution as the update will always have all elements named. I don't think I would've come up with it on my own. Cheers, e. Duncan Murdoch wrote: > On 2/15/2007 5...

I'll retract my request for help. I managed to solve the problem by calling map followed by a call to points after rescaling the cex. Its the kind of solution that deserves a head-slap. library(Hmisc) library(maps...

Apologies for the long post. This is an issue I have been struggling with and I have tried to be as complete, to the point, and reproducible as possible. In documenting a package with roxygen2, I have come across an...
