similar 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 code tasks.labels

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.

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

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"

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/R/gantproblem.pdf for the two charts. The charts were produced

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

hi every one, i have a excel sheet like this labels starts ends 1 first task 1-Jan-04 3-Mar-04 2 second task 2-Feb-04 5-May-04 3 third task 3-Mar-04 6-Jun-04 4 fourth task 4-Apr-04 8-Aug-04 5 fifth task 5-May-04 9-Sep-04 now i converted this excel sheet into csv file and i read the csv file into R with the below code. my.gantt.info<-read.csv("C:/Documents and

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

Dear R Community, I have a dataframe like this dat product1 product2 ... productn 01.1.2008 1 1 1 02.1.2008 1 1 2 . 15.2.2008 2 2 NA . 04.4.2008 2 2 1 05.4.2008 NA 2 NA (date ascending order, 1:n products with status 1, 2 or NA) and want to produce a graphic like

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 task","Fifth task"), starts

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.

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 Site : https://www.microlinux.fr Mail : info at microlinux.fr T?l. :

All Is there a package or library that will, given a nucleotide sequence 1. calculate the extinction coefficient at 260 nm for (Beer-Lambert's law) 2. calculate molecular weight 3. return it's complementary sequence I was able to find several packages that can do similar calculations for an amino acid sequence for proteins but none for nucleic acids. Any pointers, etc. would be

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.color <- "yellow" tasks <- list() #

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

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

Hi, I would like to draw a pie chart. I've already tried out the standard pie-function in the GRAPH-package. My question: is there any 'better' function or package to draw a pie chart. For example I would like to draw a 3D pie chart. Dietrich Tissen
