Question

I want to subtract the values in a vector from a scalar. However, if the result is lower than zero I want to set the result to zero.

I have tried using max, but it doesn’t give me the expected result

s
# [1]  750.0  975.0 1125.0 1237.5 1312.5 1400.0

max(1050 - s, 0)
# [1] 300

I expect result to be c(300, 150, 0, 0, 0, 0)

Answer 1

I suggest pmax:

pmax(1050 - s, 0)
# [1] 300  75   0   0   0   0
