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

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

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

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.

>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, 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"

hi everybody, How can you plot some dates? I mean how can i have the tickmarks with the label of each date on my x axis? The dates i use are in POSIXct format, i don't know if it matters. thanks a lot Karine _________________________________________________________________ Consultez vos emails Orange, Gmail, Yahoo!, Free ... directement depuis HOTMAIL !

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 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

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

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. :

Sorry, maybe it's easy but I haven't found anything useful: how can I obtain a list C that contains all the members in the list B that are not in list A? This are lists of nanes, not numbers!

Hi how can I find, in a vector of characters, which is the most frequent one?

Dear r-help mailing list, this seems stupid, but I actually don't find the solution: if I have a vector of numbers x of length n, ranging, say, from -3 to 4, if I do barplot (x) all the values below 0 go downwards, and all the positive values go upward. How can I make them all begin from the minimum pointing upwards? Thanks! Gabriele Zoppoli, MD Ph.D. Fellow, Experimental and Clinical

Hi, I want to generate a number of vectors and store them with different names, like this: x=1 while (x<100) { vector#x# = rnorm(100) x=x+1 } where each vector has, at its hand, instead of #x# a number which goes from 1 to 99. How can I do this? Thanks Gabriele Zoppoli, MD Ph.D. Fellow, Experimental and Clinical Oncology and Hematology, University of Genova, Genova, Italy Guest

Please give me just a reference where I can find something useful. In summary, I need to : - find the median of each row of a matrix - create a new matrix with each value in the first matrix divided by the median of its row - if a value "a" in the second matrix is < 1, I need to substitute it with 1/a I know that for some of you it must be overeasy, but I swear I googled for two

Hi all, if I transpose a matrix with t(data), the newly created colums do not appear to have the first row as header. How can I do to have all the newly created columns have their first row as a header?
