to_SPSS {r2spss}

Convert R Objects to SPSS-Style Tables

Description

Generic function to convert an R object into an object that contains all necessary information for printing a LaTeX table that mimics the look of SPSS output.

Usage

to_SPSS(object, ...)

to_spss(object, ...)

Arguments

object

an R object for which a to_SPSS method exists, such as objects returned by functions in r2spss.

...

additional arguments passed down to methods.

Value

In order to work as expected, methods of to_SPSS should return an object of class "SPSS_table". It should include a component table that contains a data frame, which can be supplied as the first argument to to_latex to print a LaTeX table that mimics the look of SPSS output. Additional components of the returned object define additional arguments to be passed to the "data.frame" method of to_latex.

Note

to_spss is a simple wrapper for to_SPSS, which exists for convenience.

Examples

# load data
data("Eredivisie")

# compute a Kruskual-Wallis test to investigate whether
# market values differ by playing position
kw <- kruskal_test(Eredivisie, "MarketValue",
                  group = "Position")

# convert to an object of class "SPSS_table" that
# contains the table with the test results
kw_spss <- to_SPSS(kw, statistics = "test")
kw_spss

# blank out the number of degrees of freedom to ask
# an assignment question about it
kw_spss$table[2, 1] <- "???"

# print the LaTeX table to be included in the assignment
to_latex(kw_spss)
