Hi Guru's
In my quest to understand R I have what I thought was a simple exercise that
now has me baffled. Why the error message after running this code? I am
totally baffled by the error message. I was expecting rows 1 and 3 of the x
matrix to be returned, and have not a clue as to why this becomes a subscript
difficulty. The manual was of no help in this matter.
x <- c(1:3,2:4)
x <- matrix(x, nrow = 3)
x
z <- c(1:4,1,1,0,0,1,0,1,0)
z <- matrix(z, ncol = 3)
z
x[x[,2]>= 3,]
x
z %% 2 == 1
x[z %% 2 == 1,]Error in x[z%%2 == 1, ] : (subscript) logical subscript too long
Many thanks for your assistance.
