Hi,
Using a freshly updated Version 0.3.0-prerelease+3251 (2014-05-20 23:18 UTC) of
Julia I think I noticed a different behavior of readtable(), which I hope is
not intended.
I have a small test file with data as shown below (and attached as a file at
the end of the email):
lp__,accept_stat__,stepsize__,treedepth__,n_leapfrog__,n_divergent__,mu
# Adaptation terminated
-19.8871,0.975123,0.303529,4,15,0,4.25051
-22.1208,0.971631,0.303529,3,7,0,8.55276
-23.8336,0.857954,0.303529,4,15,0,4.41087
If I remove the commented line ("# Adaptation terminated"), readtable() has no
problem, but if it's there readtable() seems to ignore the 'allowcomments=true'.
I didn't update DataFrames as far as I am aware, but once or twice today I did
pull Julia's master from github.
I wonder if someone could try this example. Thanks a lot.
