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 cha...

hi, Thanks for responding of gantt charts. but i have some problem regarding with gantt charts. i.e. Ymd.format <- "%Y/%m/%d" Ymd <- function(x){ as.POSIXct(strptime(x, format=Ymd.format))} gantt.info <- list( labels =c("First task","Second task","Third task","Fourth t...

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...

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" "2018-04-15" ... $ c3d1: POSIXct, format: "2018-04-15" &qu...

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

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 http://ca.geocities.com/jrkrideau...

Hi, I don't know to solve this error that is returned, even though I understand it: library(plotrix) Ymd.format<-"%Y/%m/%d" gantt.info<-list(labels= c("First task","Second task (1st part)","Third task (1st part)","Second task (2nd part)","Third task (2nd part)", "Fourt task","Fifth task","Sixth task"), starts= as.POSIXct(strptime( c(&q...

...ducts with status 1, 2 or NA) and want to produce a graphic like this, where 1 or 2 are colored rectangles, NAs are white: product1 11..........2............2_ product2 11..........2............22 . . productn 12.........._............1_ time_axis (=dat) -> which looks like a Gantt chart with multiple time slots. I have tried it with image() which looks good, but I don't know how to produce an y-axis with labels product1, etc. and a x-axis with date labels. Further, I want to draw a scatterplot below (using layout()) with the same x-axis. Maybe someone has a better idea...

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. Problem #1 I'm trying to use strptime to convert a datetime string (7/12/2010 5:30:05 PM) to POSIX so I can use it as a start/end t...

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, Niki -- Microlinux - Solutions informatiques durables 7, place de l'?glise - 30730 Montpezat...

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. plotfile <- "gant.eps" regular.color <- "lightgray" important.col...

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: ********* ***** **********

I have a need to use a project management software package under Centos 6.6 and have started looking at ProjectLibre which is a Java package. Unfortunately it seems to have shortcomings when it comes to following up projects and my current understanding is that it falls short of Microsoft Project 2010, i.e., a previous version. Does anyone have experience with this type of software and what

While writing a function that includes placing grid lines at the same position as the axis ticks, I found that the axis* functions don't return anything. Thus I have had to copy the appropriate function, removing the call to axis() and adding a line to return the tick positions. Is there a more elegant way to determine the tick positions on an axis? Thanks. Jim (normally bitwrit at

Hello again, First, thanks for the help that got the latest plotrix package finished. I had been planning to write something about packages since Scott Waichler offered the gantt.chart function. Then Ben Bolker (who helped me to write the axis.break function) asked if I would be willing to include some of his plotting functions and almost immediately after that Sander Oom kindly donated the soil texture plotting function in the same way. I could procrastinate no longer....
