Hi, I was wondering if someone has witnessed the following behavior with matching on multiple minimums in a vector:
If I manually create a vector of doubles: test <- c(2.33,11.09,0.02,0.02.1.7,6.41) I can then run any of the following to retrieve the indices of the minimum values (3 and 4 in this case), of which there are two (done purposefully): which(test==min(test)) or which(!is.na(match(test,min(test)))) or match(test,min(test)) # to see the entire vector However, my problem is as follows. I am not manually creating a vector to test for multiple minimums but rather doing a read.table on a file that contains the same data with other columns, etc. I then trim off the data from that matrix (there are several identical ways to do this): unlist(myMatrix[1], use.name=FALSE) or myMatrix[,1] But, running any of the tests listed above only returns the index of the last minimum. Both my manual vector and vector culled from the matrix appear to me to be identical (tested with is.vector, is.numeric, is.double, etc), but it will only every return the index of the second of the two minimums. Any help would be truly appreciated.
