Dear all,

Sweave chokes when using "\\" in the path to the Rnw file. Using "/" works fine. The problem is that Eclipse+StatET uses "\\" in the filename.
And example of the error, traceback and sessionInfo are given below.

Best regards,

To call in the statistician after the experiment is done may be no more than asking him to perform a post-mortem examination: he may be able to say what the experiment died of.

The combination of some data and an aching desire for an answer does not ensure that a reasonable answer can be extracted from a given body of data.
