I have a species as rows and sites as columns matrix. I would like to
tranpose this matrix so that I can do an NMDS analysis with the vegan
package. I have used
y <- t(x)
and it indeed transposes the matrix, but it changes the whole make up
chr [1:193, 1:288] "oligocha" "0" " 0" " 0" " 0" "0"
x <- read.table("LittleGarvin.csv", sep=",", header=TRUE)
y <- t(x)
str(y)
chr [1:193, 1:288] "oligocha" "0" " 0" " 0" " 0" "0" ...
- attr(*, "dimnames")=List of 2
..$ : chr [1:193] "X" "upwd1201" "upwd0502" "upwd0702" ...
..$ : NULL
x is a data frame with a whole bunch of numeric vectors I
5 matches
