Thanks for your suggestions. "Reproducible examples", my datasets are too
big so I'm not sure what you would want to see. Anyway, does this help:
dataset:
Perf_Index Age risk_score gender hight IQ ...
12 78 10 m 6 110 ...
10 77 9 f 6 97 ...
5 64 f 13 5 120 ...
...
varslist:
Perf_Index Age IQ ...
As you suggested
> str(varslist)
'data.frame': 1 obs. of 54 variables:
$ V1 : Factor w/ 1 level "Perf_Index": 1
$ V2 : Factor w/ 1 level "Age": 1
$ V3 : Factor w/ 1 level "risk_score": 1
...
for (i in varslist){
v<-mean(Dataset[,i])
print(v)
}
gives:
> source("/Users/jween/Desktop/test.R")
[1] 20016.06
[1] 20016.06
[1] 20016.06
[1] 20016.06
[1] 20016.06
[1] 20016.06
... 54 instances, the number of variables in varslist
Not correct, obviously. I'm guessing I've not read varslist in correctly (I
used read.table).
Cheers
Jon
