...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 ?=?.

The function produces a summary quite like: summary(lm(x ~ y + w * z)) [for instance] and I am not clear how to save this summary into a text file 'automagically', because I need to be able to do it in a for() loop.

My problem is: I have two vectors, a <- c(TRUE,FALSE,FALSE) b <- c(TRUE,FALSE,TRUE) and I would like to obtain a vector that indicates if it is TRUE in any of the two vectors. Hence, the desired output would be: TRUE, FALSE, TRUE Thank you in advance, Federico __________________________________________________ [[alternative HTML version deleted]]
