The order() function in R is used to return a permutation that simply orders or rearranges a sequence of numeric, complex, character, or logical vectors in ascending or descending order by their index positions.
order(…, na.last = TRUE, decreasing = FALSE)
The order() function takes the following parameter values:
...: This is a sequence of numeric, complex, character, or logical vectors of the same length to be ordered in ascending or descending order. This is a required parameter.na.last: This takes a boolean value (TRUE or FALSE). If TRUE, the missing value in the input data is put last. If FALSE, they are removed first and NA values are also removed. This is an optional parameter.decreasing: This takes a boolean value indicating if the sort order should be in ascending (increasing) or descending (decreasing) order. This is an optional parameter.# creating a numerical objecta <- c(100, 5, 2, 8, 10, 1, 0.5)# sorting increasinglyorder(a, decreasing=TRUE)# sorting decreasignlyorder(a, decreasing = FALSE)
