...ve values should be counted, and if the mean is <0 then only negative values should be counted. In cases where the mean is equal to zero, the value -99999 should be returned.
The following is an example of the data frame I'm working on (all values are of class 'numeric').

Finding ranges on a per-row basis from several objects
Dear all,
I'm attemping to find the overall range of values from column 5 of a series of data frames, on a per-row basis, and assign the results to a new object. At present, I'm only able to receive the overall range of all values, whereas I'm intending to get the results of the range for each corresponding row. This is what I have so far:
for (i in seq(nrow(dframe[1])))
???
