subset_lab: Subset data and save attributes.

In kieranjmartin/viewenhance: Addin for viewing data

Description

Note that this function is only designed to handle data frames Note that for large data sets this will take a long time, so by default this is only reapplied for the first 1000 columns

Usage

subset_lab(x, ..., col_lim = 1000)

Arguments

x	A data frame or matrix.
...	Other arguments passed to subset. In particular, we give subset and select arguments here (see examples and subset help for more)
col_lim	A limit on the number of columns the attributes are applied to.

Value

The subsetted data set

Examples

subset_lab(airquality, Temp > 80, select = c(Ozone, Temp))
subset_lab(airquality, Day == 1, select = -Temp)
subset_lab(airquality, select = Ozone:Wind)

## sometimes requiring a logical 'subset' argument is a nuisance
nm <- rownames(state.x77)
start_with_M <- nm %in% grep("^M", nm, value = TRUE)
subset_lab(state.x77, start_with_M, Illiteracy:Murder)
# but in recent versions of R this can simply be
subset_lab(state.x77, grepl("^M", nm), Illiteracy:Murder)
