Hi,
Consider the small dataset below, I want to subset by two variables in
one line but it wont work...it works though if I subset separately. I have
to be missing something obvious that I did not realize before while using
subset..
fish - structure(list(IDWeek = c(27L, 28L, 29L, 30L, 31L, 32L,
shouldn't you just change b to x and winter to fish? :)

As David W. guessed. The maximum is in year 2005 not 2012 so no row from
2012 matches the maximum.
subset(winter,Year==2012 Total==max(Total))
[1] IDWeek Total Fry Smolt FryEq Year
0 rows (or 0-length row.names)
winter[which(winter$Total==max
17 matches
