Installation

You can install the development version of compare as below:

library(devtools)
install_github("Fahim-Ahmad/compaRe")

Usage

library(compaRe)
compare_df(df1, df2, unique_id_df1, unique_id_df2, compare_all = TRUE)

Arguments

df1 Old version of the dataset

df2 Latest version of the dataset

unique_id_df1 unique identifier in df1

unique_id_df2 unique identifier in df2

compare_all logical. TRUE: compare all columns/variables. FALSE: compare only shared columns/variables.

Example

library(compaRe)

mtcars_v1 <- mtcars_v2 <- mtcars
mtcars_v1$id <- mtcars_v2$id <- rownames(mtcars)

mtcars_v2$am[mtcars_v2$am == 1] <- 2
mtcars_v2$wt[mtcars_v2$wt > 100] <- 105
mtcars_v2$cyl[mtcars_v2$cyl == 8] <- 7
mtcars_v2 <- mtcars_v2[1:30, ]
mtcars_v2$rowid <- 1:nrow(mtcars_v2)

compare_df(df1 = mtcars_v1, df2 = mtcars_v2,
          unique_id_df1 = "id",
          unique_id_df2 = "id",
          compare_all = TRUE
          )
          
compare_df(df1 = mtcars_v1, df2 = mtcars_v2,
          unique_id_df1 = "id",
          unique_id_df2 = "id",
          compare_all = FALSE
          )
