Dear all,
would appreciate a piece of help with a simple question: I am reading in R
a file that is formatted as a matrix (an example is shown below, although
it is more complex, a matrix of 1000 * 1000 ):
the names of the columns are 0, 10000, 40000, 80000, etc
the names of the rows are 0, 10000, 40000, 80000, etc
0 200000 400000
0 0 0 0
200000 0 0 0
400000 0 0 0
shall I use the command :
y <- read.table("file",row.names=1, header=T)
the results is :
> y[1:3,1:3]
X0 X200000 X400000
0 0 0 0
200000 0 0 0
400000 0 0 0
The question is : why R adds an X to the names of the columns eg X0,
X20000, X40000, when it shall be only 0, 20000, 40000 ? thanks !
