Dear R-help members I would be grateful if anyone could help me with the following problem: I would like to combine two matrices (SCH_15 and SCH_16, they are attached) which have a species presence/absence x sampling plot structure. The aim would be to have in the end only one matrix which shows all existing species and their presence/absence on all the different plots(an_1, an_2 etc.) To do

However I have som missing data in one of my variables (columns) and I need R to "exclude" these and make chi-square test on the data that I have.
