Thank you for that Pascal.
I changed this bit to the following:
result <- vector("list", (length(test1)-1))
for(i in 1:(length(test1)-1))
{
for(j in i+1:length(test1))
{
result[[i]][j-i] <- agrep(test1[i], test1[j], ignore.case = TRUE, value =
TRUE, max.distance = 0.1)
}
}
And now I get the error - Error in result[[i]][j - i] <- agrep(test1[i],
test1[j], ignore.case = TRUE, :
replacement has length zero
What does this mean?
