This R package allows you to easily load data from surveys. It has specfically been tested using Qualtrics surveys.

To install the package:

library(devtools)
devtools::install_github("rwash/surveys")

Loading Surveys

To load a survey:

survey <- load_survey("filename.csv")

You may see warnings -- questions that were not auto-detected. To fix these, you can add new multiple choice options:

add_multiple_choice(c("Never", "Always"), ordered=T)

You can also tell it to ignore a specific question:

ignore_question("Q15")

If you have attention check questions, you can specifically tell it which question is an attention check, and what the correct answer is:

add_attention_check("pres", "Barack Obama")

Computing Scales

You can combine multiple questions into a scale using

survey$scale <- item.scale(~Q1 + Q2, data=survey)

If you have lots of items, you can use mf() to combine them into a formula:

survey$scale <- item.scale(mf("Q", 1:20), data=survey)

There are the normal S3 functions for working with scales:

print(survey$scale)
summary(survey$scale)
plot(survey$scale)
