Hi,
The question is not clear.
set.seed(45)
spe - data.frame(Col1=sample(c(1:10,letters[1:2]),400,replace=TRUE))
mat1 - matrix(spe[,1],nrow=20,ncol=20)
#If you want to replace the non-numeric values with NAs,
mat2 - matrix(as.numeric(as.character(spe[,1])),nrow=20,ncol=20)
A.K.

str(dat2)
#'data.frame': 3 obs. of 3 variables:

Folks:
Good day. Please see the code below. three_wk_out is a dataframe with columns
wk1 through wk209. I want to change the format of the columns. I am trying the
code below but it does not work. I need $week in the for loop interpreted as
wk1, wk2, etc. Could you please help? Thanks.
