>From the help file for plotrix:
" ... x - a list of task labels, start/end times and task priorities as
returned by get.gantt.info ..."
So I try to create an object that will contain this information.
abc <- read.csv("gntr1a.csv")
# The above csv file was generated from MS .xlsx file containing the tasks and
corresponding dates
> abc
code tasks.labels start end depends done
1 101 task 1 2018/04/01 2018/04/15 NA 100
2 102 task2 2018/04/15 2018/05/31 101 50
3 103 task 3 2018/06/01 2018/06/30 102 0
> gantt.chart(abc)
Error in `$<-.data.frame`(`*tmp*`, priorities, value = numeric(0)) :
replacement has 0 rows, data has 3

Manually adding the required tasks and dates (as given in the help file
example) is not practical for my situation ....

The method to generate the most interest and attention to a question is to post
a reproducible example with a clear description of the desired "functionality".
