What is a mean with trim mean? For example, trim = 0.1....
mean(x, ...)
Default S3 method:
mean(x, trim = 0, na.rm = FALSE, ...)
Arguments
x
An R object. Currently there are methods for numeric/logical vectors and date, date-time and time interval objects. Complex vectors are allowed for trim = 0, only.
trim
the fraction (0 to 0.5) of observations to be trimmed from each end of x before the mean is computed. Values of trim outside that range are taken as the nearest endpoint.
oh yes I understand it now! what if your total n time the x% you are trying to trim is not an integer? For example, it is 1.2 or 1.9? Will it round I? for example, 1.2 will get round to 1, so trimming 1 from each end and 1.9 will get rounded to 2, so trimming 2 from each end?
