Basic Vector and Matrix Operations
...t seems as though they are probably built-in somewhere.
1) Fill out a vector to a desired length with missing values or zeros. So,
x<-c(3,4,5)
f(x,5)
3,4,5,NA,NA
2) Find the [row,col] location of a particular value in a matrix, eg
x<-matrix(1:9,ncol=3)
f(x,2)
2,1
Thanks.

Synchronzing workspaces
How do people go about synchronizing multiple workspaces on different
workstations? I tend to wind up with projects spread around the various
machines I work on. I find that placing the directories on a server and
reading them remotely tends to slow things down.
thanks,
Eric

rfImpute
...300: 26.80% 3.83% 85.37%
ntree OOB 1 2
300: 18.56% 5.74% 51.22%
Error in randomForest.default(xf, y, ntree = ntree, ..., do.trace = ntree,
:
NA not permitted in predictors
So roughFix works, but rfImpute doesn't....
Thanks,
Eric
