parsing numbers from a string
...now I want to plot the results nicely.
I don't know anything about the size of the x and y values in advance.
Plotting these values is not a problem.
However, I want to add errorbars (errbar in the Hmisc package).
1) For this I'm factoring the data (xdata00 varies from 0 to max(xdata00))
xfactor00 = factor(cut(xdata00, breaks = (max(xdata00)/10)*(0:100)))
2) I compute the means of the different levels
ymeans00 = tapply(ydata00, xfactor00, mean)
3) I compute the errors of the different levels
ystdevs00 = tapply(ydata00, xfactor00, sd)
4) And then I use the errbar function
errbar((xlim/2...
