Dates are always stored as integers, so that is expected. You would need to use as.character() to convert the date before you output it to the file, but then it won't be of type double. 

Also, thee is a general r-help list where these types of questions should go.

Hi all,

I am writing a matrix (typeof = double) into a CSV file with write.csv.

My first column of the matrix is a date in the form yyyy-mm-dd hh:mm:ss:

> a_fetchdata[1,0]

[1] "double"

My CSV file contains a sequence of integers (from 1 to x) instead of the
expected date.

How can I prevent that conversion to happen when writing into CSV?
