Does this help?
x <- c(3, 8, 5, 2, 9, 33, 21)
# the 43rd percentile
quantile(x, 0.43)
# the proportion of the distribution that is less than 7
mean(x<7)

[R] how to get the percentile of a number in a vector
Sent by:
r-help-boun...@r-project.org
I'm familiar with the quantile() command, but what if I have a specific
number that I want to know its location in a vector? I know that in
known
distributions, (for example the normal distribution), there is pnorm
and
qnorm, but how can I do it with unknown vector?
thanks in advance
