Apologetic prologue: I've looked through the mailing list for an answer to
this (since I'm sure it's trivial) but I have not been able to find a fix.
So the problem is that I want each group to have a different type of plot.
"Probes" should be points and "Segments" should be lines (preferably using
the segment plot command, but I've just been trying -- unsuccessfully --
to get lines to work).
To be exact, the data looks like:
loc val valtype mouse
1428 0.1812367 Probes 2
1439 -0.4534155 Probes 2
1499 -0.4957303 Probes 2
1559 0.2448838 Probes 2
1611 -0.2030937 Probes 2
1788 -0.2235331 Probes 2
1428 0.5 Segment 2
1439 0.5 Segment 2
1499 0.5 Segment 2
1559 0.5 Segment 2
1611 0.5 Segment 2
1788 0.5 Segment 2
1428 0.1812367 Probes 1
1439 -0.4534155 Probes 1
1499 -0.4957303 Probes 1
1559 0.2448838 Probes 1
1611 -0.2030937 Probes 1
1788 -0.2235331 Probes 1
1428 0.5 Segment 1
1439 0.5 Segment 1
1499 0.5 Segment 1
1559 0.1 Segment 1
1611 0.1 Segment 1
1788 0.1 Segment 1
* loc is the x-axis location
* val is the y-axis value
* valtype is equal to "which" had I been smart and used make.groups
* mouse is the 'cond' variable
The plot command I'm currently using is,
xyplot(val ~ loc | mouse, data = df,
groups=valtype
aspect=0.5, layout=c(3,3),
lty=0, lwd=3, type="p",
col=c("black", "blue"),
as.table = TRUE)
which gives me black and blue points for the probes/segments (I've infered
alphabetical order for the groups colors). When I change the type to
c("p", "l"), I get
xyplot(val ~ loc | mouse, data = df,
groups=valtype
aspect=0.5, layout=c(3,3),
lty=0, lwd=3, type=c("p","l"),
col=c("black", "blue"),
as.table = TRUE)
I get the exact same plot. I've tried using a few of the panel functions
I found on the list (I was particularly hopeful for
http://tolstoy.newcastle.edu.au/R/help/06/07/30363.html) but I've either
been misusing them, or they are not right for what I want to do.
If anyone knows how to get points and lines in the same panel for the two
different groups (probes/segments), I would love to hear about it.
If you further know how to use the 'segment' plot in panels for the
segments, I would really love to hear about it.
Thanks in advance!
Aaron
