get_var_info {cspp}

Get information regarding the CSPP variables

Description

get_var_info retrieves information regarding variables in the CSPP dataset. The information available includes: the years each variable is observed in the data; a short and long description of each variable; the source and citation for each variable; and a general category that describes each variable.

Usage

get_var_info(
  var_names = NULL,
  categories = NULL,
  related_to = NULL,
  exact = FALSE
)

Arguments

var_names

Default is NULL. Takes a character string. If left blank the function does not subset by variable name.

categories

Default is NULL. Takes a character string. If left blank the function does not subset by category.

related_to

Default is NULL. Takes a character string. If the user supplies a character string, the function searches the other relevant fields (variable name, short/long description, and source) for string and returns either exact or partial matches depending on the value of the exact argument.

exact

Default is FALSE. If true, exact matches for the other supplied arguments are used. If TRUE, then partial matches are also returned.

Details

Users can request this information regarding specific variables or all the variables within a specific category. Users can request exact matches of their supplied arguments or allow partial matches with the exact argument. Users can also search all these relevant fields (variable name, short/long description, source) for a keyword/s with the supply a string related_to argument to identify variables related to a topic of interest.

Specifying no arguments returns all the information for all the variables in the CSPP dataset.

# returns all variable information
get_var_info()

# searches all columns for non-exact matches of "pop" and "fem"
get_var_info(related_to = c("pop","femal"))

get_var_info(categories = "demographics")

# returns non-exact matches for variables with "pop" and that have "femal" anywhere in the row
get_var_info(var_names = "pop",
             related_to = "femal")
