Multiple lattice plots on a page: aligning x-axes vertically
Dear R-help,
I am creating a two lattice plots (a densityplot() and xyplot()) that
have the same x-axes and then 'printing' them onto the same page, one
above the other (see end of email for an example to generate the graph).
With different labels on the y-axis for each plot the left spacing is
different, and the x-axes don't align vertically. Although I can
manually modify the

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.

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"

memdisk: DOS as a PreOS
Hello!
Is it possible to load a virtual DOS Floppy with memdisk to do a few
things (e.g. scan for viruses, copy a hard disk image from the network
to the local disk) and continue booting from the local hard disk without
a reboot?
Cheers

save in for loop
Dear users,
My problem concerns save() within a for loop.
Here is my code:

temp <- data.frame(a=(i+1):(i+10), b=LETTERS[(i+1):(i+10)])
filename <- paste("file", i, sep="")
assign(filename, temp)
save(filename, file=paste(filename, ".rda", sep=""))

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.
