replyr (version 0.3.01)

replyr_filter: Filter a tbl on a column having values in a given set.

Description

Note: if temp tables can't be used a regular table is created and destroyed (which may not be safe if there is another replyr_filter running at the same time).

Usage

replyr_filter(x, cname, values, ..., verbose = TRUE,
  tempNameGenerator = makeTempNameGenerator("replyr_filter"))

Arguments

x

tbl or item that can be coerced into such.

cname

name of the column to test values of.

values

set of values to check set membership of.

...

force later arguments to bind by name.

verbose

logical if TRUE echo warnings

tempNameGenerator

temp name generator produced by replyr::makeTempNameGenerator, used to record dplyr::compute() effects.

Value

new tbl with only rows where cname value is in values set.

Examples

values <- c('a','c')
d <- data.frame(x=c('a','a','b','b','c','c'),y=1:6,
                stringsAsFactors=FALSE)
replyr_filter(d,'x',values)
