Hi Helmut and d_labes,

Sorry for late reply because i din't receive email notification i thought no one has reply to my query yet until i login just now.

I followed your instructions and yeah...finally i could get the sample size estimation !!!! so happy! :rotfl:

I dint get to try the below command because i have updated the programme to R 4.0.0

res     <- data.frame(design = rep(designs, each = length(target)),

                      target = target, n = NA, power = NA,

                      stringsAsFactors = FALSE)

When i run devtools::session_info(), this is what i get:-
