sort matrix based on a specific order
Hi I have a character matrix with 2 columns A and B, If I want to sort the matrix based on the column B, but based on a specific order of characters:
mat<-cbind(c('w','x','y','z'),c('a','b','c','d'))
ind<-c('c','b','d','a')
I want "mat" to be sorted by the sequence in "ind":
