Hi I'm new to julia - test driving as it were. I'm trying to carry out a Mann-Wihtney U test on two columns of a DataFrame.
# data available at http://www.openintro.org/download.php?file=os2_data&referrer=/stat/extras.php using DataFrames data_in = readtable("marathon.csv", header=true, separator = ',') male_data = subset(data_in, :(Gender .== "m")) female_data = subset(data_in, :(Gender .=="f")) # type DataArray has to be converted to type Array (use typeof function to see this) # for the MannWhitneyUTest using HypothesisTests mv = vector(male_data["Time"]) fv = vector(female_data["Time"]) MannWhitneyUTest(mv, fv) Using the above I get an error after running the test. no method testname(ApproximateMannWhitneyUTest,) in show at /home/iain/.julia/v0.2/HypothesisTests/src/HypothesisTests.jl:66 in anonymous at no file:945 in with_output_limit at show.jl:922 in showlimited at show.jl:944 in writemime at repl.jl:2 in writemime at multimedia.jl:41 in sprint at io.jl:434 in display_dict at /home/iain/.julia/v0.2/IJulia/src/execute_request.jl:24 HypothesisTests is installed and loaded. If I try the same without the vector conversion (I can't remember where I read about the need to convert to Array from DataArray for this!) I get the same error. I'm using julia 0.2.1 on Linux Mint (Petra). Can anyone help with this error? Thanks. Iain
