states (version 0.3.2)

compare: Compare two statelists

Description

Check set overlap between two state lists / data frames, e.g. prior to merging them.

Usage

compare(
  df1,
  df2,
  state1 = "gwcode",
  time1 = "year",
  state2 = "gwcode",
  time2 = "year"
)
report(x)

Arguments

df1

data frame

df2

data frame

state1

(character(1)) Name of the country ID var in df1, default "gwcode"

time1

(character(1)) Name of the time ID var in df1, default "year"

state2

(character(1)) Name of the country ID var in df2, default "gwcode"

time2

(character(1)) Name of the time ID var in df2, default "year"

x

a "state_sets" object produced by compare()

Details

This is a helper for interactively debugging data merges for data that may have slightly different state lists. For example, these differences in case sets could be because of country code differences.

Examples

# df2 has all countries in 2018 but some values in x1 are missing
df1 <- state_panel(2018, 2018, partial = "any")
df1$x1 <- round(runif(nrow(df1))*5)
df1$x1[sample.int(nrow(df1), size = 20, replace = FALSE)] <- NA

# df2 is missing some countries and also has missing values in x2
df2 <- state_panel(2018, 2018, partial = "any")
df2 <- df2[sample.int(nrow(df2), size = 150), ]
df2$x2 <- round(runif(nrow(df2))*5)
df2$x2[sample.int(nrow(df2), size = 20, replace = FALSE)] <- NA

comp <- compare(df1, df2)
