problem (and solution) to rle on vector with NA values
...?? y <- x[-1L] != x[-n]
in line 7 of the rle function body. In this test, NA values return logical NA
values, not TRUE/FALSE (again, unsurprising).
Resolution:
I modified the rle function code as included below. As far as I tested, this
modification appears safe. The convoluted construction of naMaskVal
should guarantee that the NA masking value is always different from
any value in the vector and should be safe regardless of the input vector
form (a raw vector is not handled since the NA values do not apply here).
rle<-function (x)
{
??? if (!is.vector(x) && !is.list(x))
??????? stop(...
