Computes the percentage of values in a vector less than or greater than (and equal to) a user-supplied value.
A numeric vector.
A single numeric value.
A string that indicates whether the percentage is for values in x
that are “greater than and equal” "geq"
, “greater than” "gt"
, “less than and equal” "leq"
, “less than” "lt"
the value in val
.
A logical that indicates whether NA
values should be removed (DEFAULT) from x
or not.
A single numeric that indicates the number of decimals the percentage should be rounded to.
A single numeric that is the percentage of values in x
that meet the criterion in dir
relative to val
.
This function is most useful when used with an apply-type of function.
## vector of values
( tmp <- c(1:8,NA,NA) )
#> [1] 1 2 3 4 5 6 7 8 NA NA
## percentages excluding NA values
perc(tmp,5)
#> [1] 50
perc(tmp,5,"gt")
#> [1] 37.5
perc(tmp,5,"leq")
#> [1] 62.5
perc(tmp,5,"lt")
#> [1] 50
## percentages including NA values
perc(tmp,5,na.rm=FALSE)
#> [1] 40
perc(tmp,5,"gt",na.rm=FALSE)
#> [1] 30
perc(tmp,5,"leq",na.rm=FALSE)
#> [1] 50
perc(tmp,5,"lt",na.rm=FALSE)
#> [1] 40
