reading a dense file of binary number

Would readLines() work?

Michael

hi all,

i have a file of the following format that i want to read into a matrix:

010101001110101
101010010111110
010010100100000
...

it has no headers or row names.

I tried to use read.table(), but it doesn't allow me to specify nothing as
the column separator (specifying sep='' means whitespace for that
function). ?read.fwf doesn't seem appropriate either.

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"

HTH,
Jorge
