Hi list,
How to save a list content into a text file?
Please consider example below, I have two numeric matrices that I
bundle into a list & give each list element a name
Example:
matrixA <- matrix(0,5,4)
matrixB <- matrix(1,7,13)
matrixList <- list(matrixA,matrixB)
names <- c("Matrix A","Matrix B")
names <- names(matrixList)
How could I get the list in a txt as below:
"
Matrix A
(Matrix A element 1,1), (Matrix A element 1,2), ...
(Matrix A element 2,1), (Matrix A element 2,2), ...
...
Matrix B
(Matrix B element 1,1), (Matrix B element 1,2), ...
(Matrix B element 2,1), (Matrix B element 2,2), ...
...
"
I reckon you can do this with two separate calls to write.table using
(.., append=TRUE).
Not the most elegant, but:
outfile <- open('output.txt', 'w')
cat("Matrix A\n", file=outfile)
close(outfile)
write.table(matrixA, file='output.txt', append=TRUE, ...)
outfile <- open('output.txt', 'a')
cat("\nMatrix B\n", file=outfile)
close(outfile)
write.table(matrixB, file='output.txt', append=TRUE, ...)
Hope that helps,
