Thanks very much for the replies.

Both suggestions worked perfectly.

That's one more step towards understanding R.

Thanks again.

[R] Row order in plot

2008-12-11 Thread qroberts

I'm new to R so forgive me if this seems like a simple question:

So I have table where the row titles are string variables. When I plot the
data with rows along the x-axis, the data is ordered alphabetically as
opposed to the order of the table.

How can I preserve the row order of the table in the plot?

Thanks in advance.

This is the format of the table as it appears in R

mice

  X  Green.1  Yellow.2 Blue.3  Gray.4
1   Base   469.5399  508.1532  487.1443  492.2544
2PBS   459.6553  474.0124  417.2651  392.9518
3 25 Mch  359.6216  418.0417  377.7020  394.2102
4 50 Mch  206.1835  262.8818  252.8041  172.0568
5   Ext.   287.4200   279.8562  287.3744  236.5091

I have been plotting Green.1 vs X as follows

plot(Green.1~X,data=mice)

The order on the x axis is alphabetical e.g 25 Mch, 50 Mch, Base, Ext., PBS

When I would like it to be : Base, PBS, 25 Mch, 50 Mch, Ext. like in the
table.
