gantt_rep: Generate Unit Spans for Repeated Measures

In qdap: Bridging the Gap Between Qualitative Data and Quantitative Analysis

Generate Unit Spans for Repeated Measures

Description

Produces start and end times for occurrences for each repeated measure condition.

Usage

gantt_rep(
  rm.var,
  text.var,
  grouping.var = NULL,
  units = "words",
  col.sep = "_",
  name.sep = "_"
)

Arguments

rm.var	An optional single vector or list of 1 or 2 of repeated measures to facet by.
text.var	The text variable.
grouping.var	The grouping variables. Also takes a single grouping variable or a list of 1 or more grouping variables.
units	The unit of measurement to analyze. One of the strings "character", "syllable", "word", or "sentence".
col.sep	The character string to use to separate pasted variables in the pasted columns.
name.sep	The character string to use to separate column names of the pasted columns.

Value

Returns a data frame of start and end times by repeated measure and grouping variable(s)

Note

For non-repeated measures data use gantt. For more flexible plotting needs use gantt_wrap over the generic plotting method.

Examples

## Not run: 
dat <- with(rajSPLIT, gantt_rep(act, dialogue, list(fam.aff, sex),
    units = "words", col.sep = "_"))
head(dat, 20)
plot(dat)

gantt_wrap(dat,  "fam.aff_sex",  facet.vars = "act",
    title = "Repeated Measures Gantt Plot",
    minor.line.freq = 25, major.line.freq = 100)

## Two facets variables
dat2 <- with(DATA2, gantt_rep(list(day, class), state, person,
    units = "words", col.sep = "_"))
head(dat2, 20)
plot(dat2)

## End(Not run)
