Pascal,
result_vector <- vector()
result <- vector("list", (length(test1)-1))
for(i in 1:(length(test1)-1))
{
for(j in (i+1):length(test1))
{
result_vector[j-i] <- agrep(test1[i], test1[j], ignore.case = TRUE, value
= TRUE, max.distance = 0.1)
}
result[[i]]<- result_vector
}
I'm not sure what the problem is with the dimension/length of result which
is a list. But I just use the second line: result <- vector("list",
(length(test1)-1))
What am I missing?
Thank you Rui Barradas.
