Maxima

Description

Returns the maxima of the inputs.

Details

Setting na.rm = TRUE will remove NA's before calculating the maxima of the values.

max(..., na.rm = FALSE)

See Also

min(), median(), mean(), quantile()

Examples

max(c(8, 3, 2, 6))
#> [1] 8

-----------------------------------

# NA's are missing values, so since the
# first element of this vector /may/ be
# greater than 6, the max of this vector
# is unknown:

max(c(NA, 3, 2, 6))
#> [1] NA

# To drop NAs, set na.rm = TRUE:

max(c(NA, 3, 2, 6), na.rm = TRUE)
#> [1] 6

-----------------------------------
