Dear R-Users: I would like to fit a multilevel model using LME such that the parameters after fitting the multilevel in two separate groups and when I use the complete data (with interactions between the grouping variable and the...

Dear all; I am trying to use HMISC imputation function to perform multiple imputations on my data and I keep on getting errors for the code given in the help files. When using "aregImpute" the error is; >f <- aregImpute(~y...

Dear R users: I have the following matrix. 0 1 1 0 1 0 2 1 0 3 0 0 I would like to spread the matrix such that whenever the row sum is greater than 1 the row is...

Dear R users, I would like to sort elements of a matrix by row and use this ordering to also sort another matrix. I am trying to post-order the means of components for a mixture model and would also...

Dear R users; I am trying to write a small program which reads in a data set, and selects observations from certain years before the analysis. I have a problem including the selection criteria in the header of the program...

Dear R users, Is it possible to use an R function accepting several arguments and returning a list in C code. I notice that in all examples only one variable is returned. Here is the C part I feel is...
