Hello,
Maybe seq(1, 16*11, 11)? (16*11 is 176, not 166)
Hope this helps,

hi there,
I have a dataframe in the shape vA1, vA2,..., vA11, vB1, vB2,..., VB11,.......,
VP1, VP2,...., VP11 (so 16 times a sequence of 11 variables)
I am trying to build a double loop so that i can apply the function (i-1)*v(i)
to the first 10 variables, then the same for the next 10 variables, etc... 16
times.
I have tried the following with no luck:
iscores<-list()
for (j in seq(1,166,11))
{
for (i in j:(j+10))
{iscores[[i-j+1]]=(i-j)*data[[i-j+1]]
}
}
any suggestion...?
many thanks,
Christel
