An internal function that helps to create a wide time series that will then be used by clim_calc within ts2clm to produce a climatology as desired by the user.

clim_spread(data, clim_start, clim_end, windowHalfWidth)

## Arguments

data The data given to this function during the calculations performed by ts2clm. The first day of the time series to use when spreading. The last day of the time series to use when spreading. The width of the smoothing window to be applied. This width is doubled and centred around the point that the smoothing occurs. Default = 5, which makes an overall window size of 11.

## Value

The function returns the data (a matrix) in a wide format.
