Using an upload of test-data/2.tabular as test dataset My local installations (Mac and Linux) of galaxy reports this error for Histogram: An error occurred running this job: Error in hist.default(list(68, 71, 62, 75, 58, 60, 67, 68, 71, 69), xlab = "V1", : 'x' must be numeric This works without error at: http://main.g2.bx.psu.edu/ I looked at the code in tools/plotting/histogram.py and it doesn't make sense to me. Why does it create matrix = [] which it seems to use as a 2-Dim array? R hist() seems to only take an R Vector. Are there any version changes to R, Rpy, or NumPy that might have changed how this operates? I executed some of that code interactively and got the same error message: $ python Python 2.6.4 (r264:75706, Mar 9 2010, 10:00:44) [GCC 4.2.1 (Apple Inc. build 5646) (dot 1)] on darwin Type "help", "copyright", "credits" or "license" for more information. ... row = [];row.append(float(i));matrix.append(row) ...
