Well, if you really want to produce what SAS does:
ageval = read.table(textConnection('AgeCat FINWT
+ 1 98
+ 2 62
+ 1 75
+ 3 39
+ 4 28
+ 2 47
+ 2 66
+ 4 83
+ 1 19
+ 3 50
+ '),header=TRUE)
one = aggregate(ageval$FINWT,ageval['AgeCat'],sum)
two = prop.table(as.table(one$x)) * 100
three = cumsum(
I am new to R. I have a data set like this (given below is a fictional
dataset):
AgeCat FINWT
1 98
2 62
1 75
3 39
4 28
2 47
2 66
4 83
1 19
3 50
I need to calculate the weighted distribution of the variable AgeCat.
In SAS i can do:
proc freq data=ageval;
tables agecat;
weight finwt;
run;
