all(..., na.rm=FALSE) any(..., na.rm=FALSE)
all
returns a
logical value indicating whether or not all of the elements of
x
are TRUE
.
The value returned is TRUE
if all the values in x
are
TRUE
, and FALSE
if any the values in x
are
FALSE
. If x
consists of a mix of TRUE
and
NA
values, then all
returns NA
.
Given a sequence of logical arguments, any
returns a
logical value indicating whether or not any of the elements of
x
are TRUE
.
The value returned is TRUE
if any the values in x
are
TRUE
, and FALSE
if all the values in x
are
FALSE
. If x
consists of a mix of FALSE
and
NA
values, then any
returns NA
.
For both functions the argument na.rm
indicates whether
NA
values should be removed before the result is computed.
range(x <- sort(round(rnorm(10) - 1.2,1))) if(any(x < 0)) cat("x contains negative values\n") if(all(x < 0)) cat("all x values are negative\n")
