Hi,
I have two table matrix, and I would like to compare the different between

For example:
Matrix 1:
A B C
A 0 1 0
B 0 0 1
C 0 0 0
Matrix 2:
A B C
A 0 1 0
B 0 0 0

Hi,
Not quite understand your question. Suppose the columns of one matrix
(matrix1) have multiple 1's while matrix 2 have only 0's, do you mean that the
difference should be 0 for that column?
Anyway, the result that you wanted for this example can be got from:
mat1<-read.table(text="
A B C
Vincent,
The root of this problem seems to be that you don't fully understand the
differences between matrix and data.frame. Read up on them and you'll know how
to solve this problem.
For now:
as.matrix(temp[,-1])
or
temp = read.csv("Weather.csv", sep=",", row.names=1)
temp1 <- as.matrix(t

Hello,
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 10 8 6
3 F
6 matches
