sjplot {sjPlot}

Wrapper to create plots and tables within a pipe-workflow

Description

This function has a pipe-friendly argument-structure, with the first argument always being the data, followed by variables that should be plotted or printed as table. The function then transforms the input and calls the requested sjp.- resp. sjt.-function to create a plot or table.

Both sjplot() and sjtab() support grouped data frames.

Usage

sjplot(data, ..., fun = c("grpfrq", "xtab", "aov1", "likert"))

sjtab(data, ..., fun = c("xtab", "stackfrq"))

Arguments

data

A data frame. May also be a grouped data frame (see 'Note' and 'Examples').

...

Names of variables that should be plotted, and also further arguments passed down to the sjPlot-functions. See 'Examples'.

fun

Plotting function. Refers to the function name of sjPlot-functions. See 'Details' and 'Examples'.

Details

Following fun-values are currently supported:

"aov1"

calls sjp.aov1. The first two variables in data are used (and required) to create the plot.

"grpfrq"

calls plot_grpfrq. The first two variables in data are used (and required) to create the plot.

"likert"

calls plot_likert. data must be a data frame with items to plot.

"stackfrq"

calls tab_stackfrq. data must be a data frame with items to create the table.

"xtab"

calls plot_xtab or tab_xtab. The first two variables in data are used (and required) to create the plot or table.

Value

See related sjp. and sjt.-functions.

Note

The ...-argument is used, first, to specify the variables from data that should be plotted, and, second, to name further arguments that are used in the subsequent plotting functions. Refer to the online-help of supported plotting-functions to see valid arguments.

data may also be a grouped data frame (see group_by) with up to two grouping variables. Plots are created for each subgroup then.

Examples

library(dplyr)
data(efc)

# Grouped frequencies
efc %>% sjplot(e42dep, c172code, fun = "grpfrq")

# Grouped frequencies, as box plots
efc %>% sjplot(e17age, c172code, fun = "grpfrq",
               type = "box", geom.colors = "Set1")

## Not run: 
# table output of grouped data frame
efc %>%
  group_by(e16sex, c172code) %>%
  select(e42dep, n4pstu, e16sex, c172code) %>%
  sjtab(fun = "xtab", use.viewer = FALSE) # open all tables in browser
## End(Not run)
