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".

Generate Unit Spans for Repeated Measures

Value

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

Description

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

Note

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

Examples

## <strong>Not run</strong>: 
# 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)
# ## <strong>End(Not run)</strong>
