Hi all,
Since two days I am trying to find a solution to be able to create
beanplots for my data. When I call the beanplot function the following
error appears:
> beanplot(y1 ~ x1, log="", what=c(1,1,1,0), ylim=c(0,1))
> Error in bw.SJ(x, method = "dpi") : sample is too sparse to find TD
What is really strange: I have 32 different vectors and the problem occurs
for about 20 of them. All of the 32 vectors contain the same number of data
values (about 20.000), within the same range, and without any NA values.
The only thing which is slightly different sometimes is the distribution.
I also had a look at the source code of the function which causes the
error:
> TD <- -TDh(cnt, b, n, d)
if (!is.finite(TD) || TD <= 0)
stop("sample is too sparse to find TD")
> TDh <- function(x, h, n, d) .C(R_band_phi6_bin, as.integer(n),
as.integer(length(x)), as.double(d), x, as.double(h),
u = double(1))$u
But this also doesn't really help me. Has anyone of you an idea what's
causing my problem and how I can avoid it? The only thing I found so far
was this thread:
