sunspot.year {datasets} | R Documentation |
Yearly numbers of sunspots.
sunspot.year
The univariate time series sunspot.year
contains 289
observations, and is of class "ts"
.
Prior to R 2.0.0 sunspot.year
and sunspot.year
were copied to the user's workspace (or elsewhere) by
data(sunspot)
. However, as package lattice has a dataset
sunspot
which can be retrieved by the same command, that usage
has been removed.
