Reduce the dimensionality of the table
collapse_table(
poptable,
area_var,
X_vars,
count_var,
report = "counts",
new_name = "n_aggregate",
warnings = FALSE
)
The population table, collapsed in terms of counts. Must contain
all variables in the RHS of formula
, as well as the variables specified in
area_var
and count_var
below.
A character vector of the area of interest.
A character vector of the variables to keep. By design, this
should be fewer variables than what is available in poptable
.
A character variable that specifies which variable in poptable
indicates the count
Should the output be in simple counts (the default, "counts"
) or
the proportion that count represents in the area ("proportions"
)?
What should the new count (or proportion) variable be called?
Show some warnings about zero cells in the original data?
Defaults to FALSE
A dataframe of counts or proportions. By design, it will include the
variables area_var
, X_vars
, and whatever is specified in new_name
.
