Hello,
See if this is it. You must reinitialize 'result_vector' just before the
loop that constructs it.
test1 <- c("Vashi", "Vashi,navi Mumbai", "Thane", "Vashi,new Mumbai",
"Thana", "Surekha", "Thane(w)", "surekhaN")
result <- vector("list", (length(test1)-1))
for(i in 1:(length(test1)-1)){
result_vector <- vector()
for(j in (i+1):length(test1)){
tmp <- agrep(test1[i], test1[j],
ignore.case = TRUE, value = TRUE,
max.distance = 0.1)
if(length(tmp) > 0) result_vector[j-i] <- tmp
}
result[[i]] <- result_vector
}
result
Hope this helps,

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.

Hello,
And another error in line 2. It should be
for(j in (i+1):length(test1))
Hope this helps,

Hi,
There is a mistake in the first line. It should be:
for(i in 1:(length(test1)-1))

Hi all.
This is my first message at R-help...so I'm hoping I have some beginner's
luck and get some good help for my problem!
FYI I have just started using R recently so my knowledge of R is pretty
preliminary.
Okay here is what I need help with - I need to know how to use agrep in a
for loop.
I need to compare elements of a vector of names with other elements of
the
same vector.
However if I use something like this:
for(i in 1:length(test1)-1)
{
for(j in i+1:length(test1))
{
result[[i]][j] <- agrep(test1[i], test1[j], ignore.case = TRUE, value
=
TRUE, max.distance = 0.1)
}
}
I get an error message saying - invalid 'pattern' argument. -* Error in
agrep(test1[i], test1[j], ignore.case = TRUE, value = TRUE, max.distance
=
0.1) : *
* invalid 'pattern' argument*
Test 1 being - c("Vashi", "Vashi,navi Mumbai", "Thane", "Vashi,new
Mumbai",
"Thana", "Surekha", "Thane(w)", "surekhaN")
This is the first time I'm using agrep, I do not understand how it works
fully...
Kindly help...
Thank you.
Su.
