Dear all,
I have another small scripting-beginner problem which you hopefully can
help:
I compute new variables with:
# Question 1
results$q1 - with(results, q1_1*1+ q1_2*2+ q1_3*3+ q1_4*4+ q1_5*5)
# Question 2
results$q2 - with(results, q2_1*1+ q2_2*2+ q2_3*3+ q2_4*4+ q2_5*5)
# Question 3
I think this does what you are looking for:
dta - data.frame(q1_1=rep(1,5),q1_2=rep(2,5),q2_1=rep(3,5),q2_2=rep(4,5))
for (i in 1:2) {
e1 - paste(q,i,_1 + q,i,_2 * 2,sep=)
assign(paste(q,i,sep=),with(dta,eval(parse(text=e1
}
