corr_plot: Create correlation plots of CSPP data

In cspp: A Tool for the Correlates of State Policy Project Data

Create correlation plots of CSPP data

Description

corr_plot takes CSPP data from get_cspp_data and returns either a correlation matrix or correlation plot.

Usage

corr_plot(
  data = NULL,
  vars = NULL,
  summarize = TRUE,
  labels = TRUE,
  label_size = 3,
  colors = c("#6D9EC1", "#FFFFFF", "#E46726"),
  cor_matrix = FALSE
)

Arguments

data	A dataframe. If data is generated by get_cspp_data function, the function can automatically parse the dataframe. Otherwise, this function will attempt to make a correlation plot or matrix from all numeric variables within the passed dataframe.
vars	Default is NULL. If left NULL, uses all variables within the passed dataframe. Otherwise, must be a character vector. The dataframe is subset based on variables listed.
summarize	Default is TRUE. If TRUE, and if the variable st is present, the function will create state specific averages for each variable in the dataframe. If FALSE, the function will generate the correlation matrix and plot for all values in the dataset.
labels	Default is TRUE. If TRUE, the correlation plot will include labels for the correlation value. If FALSE, no labels will be present.
label_size	Default is 3. Controls the size of the font for labels.
colors	Specify the colors to be used in the correlation plot. Must include three values in a character vector format. The default values are 'c("#6D9EC1", "#FFFFFF", "#E46726")'.
cor_matrix	Default is FALSE. If set to TRUE, instead of returning a ggplot object that is a correlation plot, returns a correlation matrix. This is particularly useful if you want to customize the output with ggcorrplot.

Details

This function is a wrapper that passes a dataframe to the ggcorrplot::ggcorrplot function which generates correlation heat plots.

Value

ggplot2 object or correlation matrix

 "innovatescore_boehmkeskinner", "citi6013", "ranney4_control", "h_diffs"),
 cor_matrix = FALSE)
