[R] gantt chart for dataset
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
=Ymd(c(2004/01/01,2004/02/02,2004/03/03,2004/05/05,2004/09/09)),
ends
=Ymd(c(2004/03/03,2004/05/05,2004/05/05,2004/08/08,2004/12/12)),
priorities =c(1,2,3,4,5))
gantt.chart(gantt.info,main=Calendar date Gantt chart)
the above code is fworking for individual varibale, that variables we have
to specify manually for each variable.
but my question is assume that above data stored in a excel file 'sample'.
now i want gantt chart for the 'sample' dataset.

Re: [R] Re ad and merge a number of .xls files into one dataframe
christiaan pauw-2 wrote: Hi everybody I have a large number of Excel speadsheets that I want to merge into one R dataframe to process. I can read them one by one with read.xls but I really need a function to read a whole directory at once and merge the columns with the same name into a single dataframe. here is what I have thus far (on Mac OS X 10.5.2. for R 2.8.0): # Define the directory where the data is path=/Users/home/mydata/ # Make a list of the filenames (they are all .xls so no need for a regular expression seekig out ones ending in .xls ) files=list.files(path=/Users/home/mydata/) # Read them into a list called data data=tapply(paste(path,files,sep=),files[1:length(files)],read.xls) This gives the data in a list. What I want is a dataframe. I can turn it into a matrix with as.matrix() but that only has one column which is more or less the same as a list. I have tried to merge different parts of the list : mdata=date.frame(merge(data[[1]],data[[2]])) but that gives an empty data frame (with the correct variable names). Even if it worked I need a way to do that with a large number of file (i.e. not manualy). I also tried to use lapply with merge as function but that didn't work either Does anyone have any ideas?
