Dear R community members,
I think I am asking a very simple question, but I really looked up in
the faqs and manuals and found nothing helpful.
I am trying to plot a data frame with the following structure (this is
just a small extract):
glo conc odor line series X1 X2 X3 X4 X5
X6 X7 X8 X9 X10 X11 X12 X13
1 0 AIR LN1 UP -0.488 -0.242 -0.143 0.008 0.142 0.075
-0.031 -0.077 0.095 -0.345 -0.187 0.201 0.524
2 0 AIR LN1 UP 0.482 0.209 0.448 0.338 0.295 0.140
0.157 -0.043 -0.341 -0.601 -0.517 -0.335 0.070
5 0 AIR LN1 UP -0.294 0.214 0.409 0.048 0.198 -0.081
0.001 -0.005 -0.136 -0.572 -0.286 0.021 -0.042
7 0 AIR LN1 UP -0.488 -0.203 0.104 -0.123 0.112 -0.140
0.049 -0.016 -0.080 -0.130 0.105 0.272 0.882
1 0 AIR LN2 UP -0.643 -0.038 -0.201 -0.089 0.113 -0.055
0.013 0.012 -0.064 -0.063 0.123 0.002 -0.099
2 0 AIR LN2 UP -0.510 0.364 0.619 0.565 0.634 0.167
0.209 -0.300 -0.615 -0.528 -0.400 -0.623 -0.312
5 0 AIR LN2 UP 0.350 0.737 0.183 0.563 0.406 0.169
-0.155 -0.189 0.036 0.051 0.297 0.014 -0.380
7 0 AIR LN2 UP -0.450 -0.234 -0.526 -0.587 -0.068 -0.187
0.124 0.070 0.141 0.159 0.356 0.505 0.648
Where the first 5 columns (glo, conc, odor, line, series) are different
categorizing factors and the rest are values of a variable over time.
I would like to plot the values of the independent variable over time
with one line for each of the groups defined by the categorical factors.
I have tried something like extracting the time series for a particular
group with, for example
data[1,6:18] and plotting that against a vector time=c(1:13), but that
does not work.
Is there any way of making such a plot or should I rearrange the data so
that time is also a factor specified by a column?
Thank you very much in advance.
Ana
