Apply a statistic to the data from each well in a plate

1	analysePlate(x, wellcol="well", wellrange, statfun, platename, plotdir=".", ...)

`x`	data frame. It must contain a column whose name is the value of `wellcol`, and further columns that are needed by the function named by `stat`.
`wellcol`	character of length 1. Name of a column in `x` that contains the well ID.
`wellrange`	vector of the same type as `x[, wellcol]`. All values `x[, wellcol]` must be contained in `wellrange`.
`statfun`	character of length 1. Name of a function that can calculate a statistic from selected rows of `x`.
`platename`	character of length 1. The name or ID of this plate, which will be used for graphics output filenames and as the value of the column `platename` of the return value.
`plotdir`	character of length 1. The name of directory where diagnostic plots will be saved.
`...`	further arguments that are passed on to `statfun`.

The semantics of this function are similar to tapply, but some additional checking and reporting is performed, and the return value is a data frame.

A data frame with number of rows equal to length(wellrange). Rows (wells) for which there is no data contains NAs. The columns comprise platename, well-ID (from x[, wellcol]), and the results from statfun.
