[R] Creating dataframe names on the fly?
I am aware that it is easily possible to create var names on the fly. e.g.
assign(paste("m",i,sep=""),j)
but is it possible to assign dataframes to variables created on the fly?
e.g.
If I have a dataframe called master and I wanted to subset parts of those
data into separate dataframes, I could do:
m1=subset(master,master$SAMPLE=='1')
m2=subset(master,master$SAMPLE=='2')
.
but I would like to do this in a loop. Can someone give me suggestions on
how to accomplish this?
I tried assign(paste("m",i,sep=""),subset(master,master$SAMPLE==i) with no
success.
thanks!

[R] memory corruption in R
HI... I am using R-package CORElearn ( http://cran.r-project.org/web/packages/CORElearn/index.html). During its application on a dataset, It crashed. The crash message says *** glibc detected *** /usr/local/lib64/R/bin/exec/R: malloc(): memory corruption: 0x4b9b0788 *** The error log "cdump.dat" is attached. I am using R-3.1.1 and CORElearn version is 0.9.43 May I know where is the problem?

Re: [R] memory corruption in R
The CORElearn crashed when I used a test file of 100MB for the analysis. However, it was difficult to send this big file to the developer, so I sent a smaller test file ( ~40MB) to the developer. With this file, the CORElearn did not crash. So, now I am now running the code with the same (~40MB) test file to see it again crashes. It will take sometime to finish.

[R] Error while using rfImpute
Dear Administrator,
I am using linux (suse 10.2). While attempting rfImpute, I am getting the
following error message:
> Members <- rfImpute(Status ~ ., data = Members)
Error in .C("classRF", x = x, xdim = as.integer(c(p, n)), y =
as.integer(y), :
C symbol name "classRF" not in DLL for package "randomForest".
I need the help to sort out above error.
Thanks a lot
Regards
Mradul

Re: [R] RStudio 1.1.453 - Windows 10 - How to subset named vector by names that are NOT "foo"
You can do
Vect[-grep (“foo”, names(vect))]
