Hi John,
yes, you are right. Here is what I have done:
plot(DateJonEnd1, End1Jon,
main=Weekly Training at Endurance 1, xlim=c(13700,14750),
xlab=Date,
ylim=c(0,350), ylab=Volume at Endurance 1, type=b, las=1)
This gets you to a matrix, though it is messy and you would still have
to convert some of the columns from character to numeric, but maybe it
will give you an idea.
matrix(data = unlist(strsplit(x = readLines(textConnection(
A 1 101 M 55 5 A 1 104 F 27 0 A 1 106 M 31 35
A 1 107 F 44 21 A
There is a much simpler way.
con - textConnection(
A 1 101 M 55 5 A 1 104 F 27 0 A 1 106 M 31 35
A 1 107 F 44 21 A 1 109 M 47 15 A 1 111 F 69 70

Hi there,
I need to merge/bind two time series objects (from RPackage: timeSeries) by
column. The theory is laid out nicely, even for overlapping indices.
In my example, I have overlapping indices (01.01.2001), where in one time
series I have one data point and in the other redundant data.
Okay, great. Thanks.
Cheers,
Marius

Hi all,
I've got two persp plots with Identical X and Y's, and I'd like to plot them
on the same graph, so that it is obvious where one plot is above the other.
I can't find any mention of this anywhere. Do I need to use wireframe?
Any help is appreciated.
Thanks,

Hi all.
I have been trying to plot 9 bubble plots on each page of a PDF file. For
this, I'm using :
par(mfcol = c(3,3), mar = c(3,3,3,3), oma = c(0,0,0,0));
However, when plotting the bubble plot (gstats package), it plots the graph
on a full page. I tried to plot something else with

There is a manual on the R website about data import and export that
