Hi, I have several data sets which are all approximately within the same values as each other (both X and Y) and all of these data sets more or less overlap each other when plotted on the same graph. However, although each data set varies between approximately the same range, there are vastly different numbers of data points within each data set (due to the nature of how these values had to be measured). Currently, I am trying to figure out a way to produce a graph showing all these data sets and a line showing the average of all of the data sets. Given the different number of data points, I can't think of an easy way to do this.
Have a look at ?approxfun Peter Ehlers
Can anybody help? Thanks!
