Or do you want each number separated?
> data <- textConnection("010101001110101
+ 101010010111110
+ 010010100100000"
+ )
> result <- as.matrix(read.fwf(data, rep(1, 15)))
> result
V1 V2 V3 V4 V5 V6 V7 V8 V9 V10 V11 V12 V13 V14 V15
[1,] 0 1 0 1 0 1 0 0 1 1 1 0 1 0 1
[2,] 1 0 1 0 1 0 0 1 0 1 1 1 1 1 0
[3,] 0 1 0 0 1 0 1 0 0 1 0 0 0 0 0

Hi Brian,
Take a look at ?scan
> x <- scan(file.choose(), what = 'list')
Read 3 items
> x
[1] "010101001110101" "101010010111110" "010010100100000"
> as.matrix(x)
[,1]
[1,] "010101001110101"
[2,] "101010010111110"
[3,] "010010100100000"
