Convert a dataframe to a Praat TextGrid.
df_to_tier(df, textgrid, tier_name = "", overwrite = TRUE)
| df | an R dataframe object that contains columns named "content", "time_start" and "time_end" |
|---|---|
| textgrid | a character with a filename or path to the TextGrid |
| tier_name | a vector that contain a name for a created tier |
| overwrite | a logic argument, if |
If overwrite is FALSE, then the function returns a
vector of strings with a TextGrid. If overwrite is TRUE, then
no output.
