Gantt Chart Using Plotrix
Hi
I am trying to generate a complex Gantt chart using the gantt.chart function in the plotrix package.
Ideally I would like to use a spreadsheet to populate the activities (tasks) and start and end dates that this function expects and then export the spreadsheet file as a .CSV text file so I can read in this file to generate the gantt chart. Reading through the help file I have not been able to

Gantt Chart Using Plotrix
Hi,
The help file for gantt.chart states that dates must be in POSIXct
format, and the example shows how to do that. There's no reason that I
can see that you can't use a data frame as input to gantt.chart, but
you need to be very careful that your data frame matches the correct
format. I bet also that your character fields were imported as
factors, because you didn't specify not to.

Gantt Chart Using Plotrix
>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

Gantt Chart Using Plotrix
Hi,
Your attempt didn't work because you didn't do what I suggested, which
was make sure that your data frame matched the example given in the
help for gantt.chart.
Here's what you have:
> str(cdfg)
'data.frame': 3 obs. of 3 variables:
$ c1d1: Factor w/ 3 levels "task 1","task 3",..: 1 3 2
$ c2d1: POSIXct, format: "2018-04-01"

Gantt chart problem after upgrade to R 2.4.0
I am having a problem with a gantt chart since
moving to R2.4.0. from 2.3.1
I made some adaptations to the code from
http://addictedtor.free.fr/graphiques/RGraphGallery.php?graph=74
and successful produced a simple gantt chart. However
when I upgraded to 2.4.0 it no longer works as
desired. See

Simple Gantt like chart for numbers rather dates
I would like to produce a chart that looks like a Gantt chart (or
shingle plot), but instead of tasks you have variable names and
instead of start and finish dates you have an upper and lower numeric
value.
If that makes sense, is there an obvious way of doing this.
Thanks,
Graham

Gantt Chart Using Plotrix
Hi Sarah
Thank you very much for your pointers.
Is there a way to specify the date string as POSIXct when reading in?
I have tried the following (very inelegant way) and still have no luck.
--- Begin Code ---
# 1st read in the spreadsheet with stringsAsFactors set to FALSE
> abc <- read.csv("gntr1.csv", header=TRUE, stringsAsFactors=FALSE)
> abc
code tasks.labels

Formatting datetime data for gantt.chart.
Overall goal:
I'd like to have a visual representation of when certain computer applications are running over the course of a day (data will come from a SQL query later, but I'm using a csv for now). My idea is to use a gantt chart, but I'm running into issues with the start and end time. I'm wondering if it's because I need to use hours instead of days as my unit of time.

Gantt chart software for CentOS 7 ?
Hi,
I'm looking for a Gantt chart software that I can install easily on
CentOS 7. I prefer EPEL - or some other third party repo - packages than
some obscure installation script for home directories.
Any suggestions ?
Cheers,

Code contributed for a gant (Gantt) chart
I searched CRAN for material on gant (or Gantt) charts, those schedule
plots that look like horizontal barplots where the x-axis is time.
Finding none, I wrote the following and am submitting it to the archive
so that it may help someone in the future.

R graphics question: "binary" bar chart
Hello!
I would like to visualize the hospitalization within one year of several
patients using a bar chart. For each patient the stay in a hospital
should be illustrated with a dark colour a if there is a stay at home
between 2 hopital stays, it should be illustrated with a bright colour.
e.g.

barplot with chopped bars
Dear R users,
I want to make a barplot with bars that can be non-continuous. An example
will be the presence and absence of some events over time, e.g. a bunch of
people that are either in the office or not in the office, for some period
of time. I want to visualize this in a bar plot like this:
Person 1: ********* ******** *******
Person 2: ********* ***** **********

coplot =? gannt chart + bargraph
I would like to display some results from simulations in the form of a
Gantt chart (progress) with a barchart (production) of another variable
below (something very similar to coplot charts). I'm not sure if I should

graphics features) or if there's a similar feature in one of the existing
packages.
