Dear all,
I have been using the graph package until last week, especially the functions

noticied that graph package is no longer on R repository although can
Dear all,
Sorry to insist in this, but I am passing really bad times trying to
solve the problem. Just to remember you:
I am tryng to solve a nonlinear optimization probel using the solnp function.
I have different datasets. For the smaller I get full solutions, for
the bigger I got an error

Dear,
I am using the solnp command (package Rsolnp) for a problem with
equality and inequality constraints.
I am not getting convergence for my problem but apart that I get 1
warning per iteration saying: ?In cbind(temp, funv) : number of rows
of result is not a multiple of vector length
Hi all,
Basically I have 2 data frames with equal dimension and I want to apply the
wilcox.test to compare columns in the same position (i.e. 1st of df.A with 1st
of df.B, 2nd of df.A with 2nd of df.B,...).
Anyone give me an hint on this, as I think it is nicer to avoid loops,
specially for

Hi all,
I am not a skillful R programmer and has I am handling with large dataframes
(about 3 x 300) I am in need of an efficient function.
I have 4 dataframes with the same dimension. I need to generate other dataframe
with the some dimension than the others where in each position it
