Re: [R] read.table or read.csv without row index?

Hi, I have the same problem as Wong. I have a csv file that contains weather observation (rows) by days (in columns). I open using: > temp = read.csv("Weather.csv", sep=",") and read: X X1.Jan X2.Jan X3.Jan X4.Jan 1 Min 2 3 4 1 2 Max 6

Re: [R] read.table or read.csv without row index?

You need to convert to a matrix and remove names: > x <- read.table(textConnection("M1 M2 M3 M4 M5 M6 M7 M8 M9 M10 + 1 9 11 14 15 18 20 20 20 20 20 + 2 3 4 8 9 11 12 14 15 15 15 + 3 4 5 8 8 9 9 9 9 9 9 + 4 4 5 7 8 8 8 8 8 8 9"), header=TRUE) > closeAllConnections() > y

[R] read.table or read.csv without row index?

Hello all, Probably my concepts about the data.frame and matrix and array in R are not clear, I need some clarification to help me understand them better. >M <- read.table("test1.csv",sep=",",row.names=NULL,header=T) gives me: M as M1 M2 M3 M4 M5 M6 M7 M8 M9 M10 1 9 11 14 15 18 20 20 20 20
