Question

I\'ve used read.table to read a file that contains numbers such as 0.00001

when I write them back with write.table those numbers appear a

Answer 1

If the input is a mixture of scientific notation and explicit notation numbers, then you will be writing your own parser to read in the numbers and keep track of which ones were in which formats. In fact, you'll want to keep a string representation of those numbers lying around so you can write back exactly what was in the input.

However, if you just want to write.table() with consistently explicit notation, try.

    write.table(format(_your_table_here_, scientific=FALSE), ...)
