The package allows the user to load and work with the dataset using the R programming language. Crucially, it incorporates the entire codebook into the dataset, which allows for easier filtering, finding units and sources, etc.

Example use

library(csp)
library(ggplot2)

data(csp, package = "csp")
dim(csp)
names(csp)
csp[1:2, ]
df <- subset(csp, variable == "real2_pc_inc_quar")
df$value <- as.numeric(df$value)

ggplot(df, aes(x = year, y = value, color = state)) +
  geom_line(show.legend = FALSE) +
  scale_color_grey() +
  theme_light() +
  labs(x = NULL, y = NULL,
       title = df$var_desc[1],
       subtitle = df$var_long_desc[1])
