Thank you all again. It works with :
library("gtools")
dat[mixedorder(A),]
considering :
A = c("A1","A10","A11","A2")
B = c(1,2,3,4)
dat = data.frame(A,B

Nonsense! Look at the results of your code -- you have failed to order
the results as had been requested by the OP. It's also unnecessarily
complicated. The following suffices (where I have used regular

Bogdan,
Follow my suggestion.
letter <- substring(A, 1, 1)
number <- substring(A, 2, nchar(A))
new.data <- paste0(letter, formatC(as.numeric(number), width = 2, flag =
"0"))

Dear all,
I am looking for a suggestion please regarding sorting a dataframe with
alphanumerical components :
let's assume we have :
A = c("A1","A10","A11","A2")
B = c(1,2,3,4)
C = data.frame(A,B)
how could I sort C data.frame in such a way that we have at the end :
C$A in the order : "A1", "
