Hello, I run a fisher.test() in a loop, with the issue that some of the data will not be useable. To protect the loop I used tryCatch but:
sexsnp = rep(NA, 1750) for(i in 1:1750){tryCatch(sexsnp[i] = fisher.test(table(data[,3], data[,i + 38]))$p, error = function(e) print(NA))} Error: unexpected '=' in "for(i in 1:1750){tryCatch(sexsnp[i] =" But this works: for(i in 1:1750){tryCatch(sexsnp[i] <- fisher.test(table(data[,3], data[,i + 38]))$p, error = function(e) print(NA))} [1] NA [1] NA [1] NA The only difference is the use of �=� or �<-� to assign the p value of the fisher test to the vector. I stopped using �<-� eons ago so it took a bit to figure out. Tested on R 4.1.2 on ContOS 8 , and on R 4.3.0 on a M1 mac with the same result. I�d be obliged if someone can explain why tryCatch assigns items with �<-� and not �=�. Cheers F Federico Calboli Tutkija Genomiikka ja jalostus Luonnonvarakeskus [[alternative HTML version deleted]]
