We have examples to demonstrate how to recode variables with the recodeflow function rec_with_table()
Our examples use following packages.
Package recodeflow Steps on how to install recodeflow are in how to install
#Load the package
library(recodeflow)Package dplyr to combine datasets (function: bind_rows).
library(dplyr)Example data Our examples use the dataset pbc from the package survival. We’ve split this dataset into two (tester1 and tester2) to mimic real data e.g., the same survey preformed in separate years. We’ve also added columns (agegrp5 and agegrp10) to this dataset for our examples.
In our example datasets, the variable sex contains the values: m for males and f for females.
Using dataset tester1, we’ll recode the variable sex into a harmonized sex variable. The harmonized sex variable has the values: 0 for males and 1 for females.
sex variable in tester1.sex_1 <- rec_with_table(data = tester1,
variables = "sex",
variable_details = variable_details,
log = TRUE,
var_labels = c(sex = "sex")
)

Use set_data_labels() to label the variables in your final dataset. set_data_labels() sets the labels with the original information in variables and variable_details.
labeled_sex_combined <- set_data_labels(
data_to_label = sex_combined,
variable_details = variable_details,
variables_sheet = variables
)You could have a situation a variable is the same across datasets but its categories change.
In our example data the variable agegrp is different in tester1 and tester2.
agegrp variable is 5-year age groups: 20-24, 25-29, 30-34, etc.agegrp variable is 10-year age groups: 20-29, 30-39, 40-49, etc.There are three options to facilitate the use of variables with inconsistent categories across datasets.
agegrp variable into a common variable for only datasets with the same category responsesRecode the agegrp variable into a common variable only in datasets were the categories are the same. If the categories are different between datasets, separate columns will be created.
The categories in the agegrp variable in tester1 are different than the categories of agegrp in tester2. Therefore, it is not possible to have the same agegrp categories across our example data sets.
