Hi Folks,
I have data that looks like this:
freq gender xBar
1000 m 2.32
1000 f 3.22
2000 m 4.32
2000 f 4.53
3000 m 3.21
3000 f 3.44
4000 m 4.11
4000 f 3.99
I want to plot two lines (with symbols) for the two groups "m" and
"f". I have tried the following:
plot(xBar[gender=="m"]~freq[gender=="f"]) followed by
lines(xBar[gender=="m"]~freq[gender=="f"])
with different symbols and lines colors (which I know how to do).
However, these initial plots are not giving me the right output. The
initial plot command generates the following error.
Error in plot.window(xlim, ylim, log, asp, ...) :
need finite 'xlim' values
In addition: Warning messages:
1: no non-missing arguments to min; returning Inf
2: no non-missing arguments to max; returning -Inf
3: no non-missing arguments to min; returning Inf
4: no non-missing arguments to max; returning -Inf
A second issue, I would also like to offset the second set of points
along the x-axis so that the error bars will be visible.
Any help is appreciated.
Regards,
Sumit
