Dear All,
It is difficult to summarize the question in few words. So, please,
look at the following example.
Thanks in advance,
domenico
----------------------------------------------------------------------------------------------------------------------------------------------------------
rm(list = ls())
posfix=1:5* 10
for(i in posfix)
assign(paste("matX.",i,sep=""),matrix(0,3,2))
ls()
[1] "i" "matX.10" "matX.20" "matX.30" "matX.40" "matX.50" "posfix"
AT THIS STEP I HAVE 5 MATRIX OF ZEROS (3 ROWS PER 2 COLUMNS)
NOW I WOULD LIKE TO ASSIGN TO A ROW OF THE 5 MATRICES A VALUE
RELATED TO THE INDEX OF A FOR LOOP
for(i in 1:length(posfix))
assign(paste("matX.",posfix[i],"[",i,",]",sep=""),i)
ls()
[1] "i" "matX.10" "matX.10[1,]" "matX.20" "matX.20[2,]"
[6] "matX.30" "matX.30[3,]" "matX.40" "matX.40[4,]" "matX.50"
[11] "matX.50[5,]" "posfix"
??????????????????
WHY IT DOES NOT ASSIGN THE VALUE TO THE ROWS OF THE PRE-INITIALIZED
VARIABLES. WHERE IS MY ERROR?
