Dear All,
I need to introduce new distribution for the error components of a frontier
model. For this reason, I use the package Frontier 4.1, but I need to
introduce other distribution function than Normal and Half-Normal (that are
those given by default).
I hope that someone help me.
Thanks.

1) What kind of file is a .dta?
2) Do you have more RAM than R is using? Check this with ?memory.limit
3) Are you on a 64 bit OS with 64 bit R?
I can tell you that starting R with --max-mem-size=
may help, but you probably want to look into R interfaces with databases
first.

Dear All,
I am an Italian researcher in Economics. I work with large sample data. I
need to increase the memory in R-project in order to upload a file ".dta".
How can I do this?
Thank you.

Hi Deepayan,
Meanwhile I found another solution by simply creating more steps within the
colorscale, so one could not notice when the colours mismatch one or two
units. Your solution is more elegant though.
