hi,

i am having trouble getting a particular time series to plot. this is what i
have:

> class(irradiance)
[1] "ts"
> irradiance[1:30]
  197811   197812   197901   197902   197903   197904   197905   197906
1366.679 1366.729 1367.476 1367.739 1368.339 1367.883 1367.916 1367.055
  197907   197908   197909   197910   197911   197912   198001   198002
1367.484 1366.887 1366.935 1367.034 1366.997 1367.310 1367.041 1366.459
  198003   198004   198005   198006   198007   198008   198009   198010
1367.143 1366.553 1366.597 1366.854 1366.814 1366.901 1366.622 1366.669
  198011   198012   198101   198102   198103   198104
1365.874 1366.098 1367.141 1366.239 1366.323 1366.388
> plot(irradiance[1:30])
> plot(irradiance)
Error in dn[[2]] : subscript out of bounds

so, if i plot a subset of the data it works fine. but if i try to plot the
whole thing it breaks. the ts object was created using:

irradiance = ts(tapply(d$number, f, mean), freq = 12, start = c(1978, 11))

and other ts objects that i have defined using basically the same approach
work fine.

any ideas greatly appreciated!

cheers,
andrew.
