Hello R users,
I want to readout the row and column postion from a certain matrix value
into a csv file.
I have only found this syntax
"which(a == b, arr.ind = T)"
so I get
a = matrix
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8]
[1,] 1 1 2 2 2 1 1 2
[2,] 1 2 3 3 3 4 4 3
[3,] 3 3 3 5 5 6 5 4
[4,] 4 4 4 3 3 4 4 3
[5,] 3 4 5 3 3 3 2 2
[6,] 3 3 3 3 3 3 2 2
[7,] 2 2 2 2 2 4 2 1
[8,] 1 1 0 0 0 0 0 0
> print(max(a))
[1] 6
> which(a == max(a), arr.ind = T)
row col
[1,] 3 6
but I need row and col seperate for the csv file.
row <- c("code for row")
col <- c("code for col")
value <- c("6")
#dataframe
test <- data.frame(row, col, value)
write.csv................
Thanks.
