When one inserts a function using “Insert Formula” the name of the function and the help message describing the function are sometimes not aligned. So for example “PolyPoints” and"PolyReg" have each other’s help messages (they are swapped) and the same swapping occurs for trimMean and Trend. In the help message trimMean is spelt “treamMean”. Just to let you know in case you have not noticed.
