Form row and column sums and means for multiple vectors, numeric arrays (or data frames) conditional on the number of non-missing observations.
rowMeansCond(..., minobs = 1L)
... | a series of numeric vectors, arrays, or data frames that have can be combined with cbind |
---|---|
minobs | an integer stating the minimum number of non-NA observations necessary to compute the row mean. Defaults to 1. |
A numeric vector containing the row sums or NA if not enough non-NA observations are present
