qualtricsMatrix: qualtricsMatrix

In mnblonsky/REMI: REMI: EMI Consulting's Internal R Package

Description

Runs a desired function on an array of columns of a data frame with similar column names (ex. Q_1_1, Q_1_2, ..., Q_2_1, Q_2_2, ...). Defaults are useful for Qualtrics data structures.

Usage

qualtricsMatrix(df, q, id1, id2, dfQuestions, func = NULL, remove = c(NA,
  NaN, NULL, "", "-99"), questionChar = "-", charInQ = 0, charInCol = 0,
  ...)

Arguments

df	main data frame
q	string representing question name (ex. "Q")
id1	vector specifying the row numbers (1,2,3...)
id2	vector specifying the column numbers (1,2,3...)
dfQuestions	data frame with same columns as df - contains question strings
func	function to run on cleaned data. An example could be fixing text (removing a ":") or converting to a different class. Default is no function.
remove	vector of strings/objects to remove from each column (ex. NA, NaN)
questionChar	character to help specify data in the question. Default is "-", which Qualtrics uses to show the question options.
charInQ	number of times that questionChar shows up in the unused part of the question.
charInCol	number of times that questionChar shows up in the column names part of the question (the last part).

Value

a data frame containing one row for each response that was not removed. The data frame can be quickly summarized or tabled, or graphed using EMI functions.
