dataequalizer {sampcompR}

Equalize dataframes

Description

dataequalizer compares two data frames and looks if both data frames contain columns with the same Name. A copy of source_df is returned, containing only columns named identical in target_df and source_df data frames. The function is mainly used in the other functions of the package.

Usage

dataequalizer(target_df, source_df, variables = NULL, silence = FALSE)

Arguments

target_df

A data frame

source_df

A data frame containing some column-names named equally in target_df

variables

A vector to indicate variable names that should be in the copy of the source_df if they are also in the target_df.

silence

A logic value. If FALSE, warnings will be returned indicating, what variables where removed, from the survey.

Value

Returns a copy of source_df containing only variables with names contained also in the target_df data frame.

Examples

## Get Data to equalize 
card<-wooldridge::card

##reduce data frame
card2<-card[c("id","age","educ","fatheduc","motheduc","IQ","wage")]

card_equalized<-sampcompR::dataequalizer(card2,card,variables=c("age","educ","IQ","wage"))
card_equalized[1:20,]
