Greetings,
I am using library(survey) to analyze some complex sample data. After
fitting a model I tried to use termplot() with make.panel.svysmooth(), but
I received an error (see below).
Could someone help me interpret the error message so I can make the
necessary corrections? The make.panel.svysmooth() function seems to work
fine, and termplot() worked fine after I dropped the smoother. This led me
to believe that the error is coming from panel.smooth(), but the code for
that function does not contain the rowsum() and findInterval() functions
shown in the error message. I should also note that error does not depend
on the inclusion or omission of missing data, as I tried it both ways.
I'm analyzing private data, so I can't provide a reproducible example, but
here's the output:
#################### design <- svydesign(ids=~PSU, weights=~W,
strat=~STR, nest=T, data=data) model <- svyglm(fmla, design=design)
#works fine as evidenced by summary (not shown) termplot(model,
data=model.frame(design), partial.resid=T, se=T,
smooth=make.panel.svysmooth(design))
Waiting to confirm page change... Error in rowsum.default(c(rep(0, ngrid),
w), c(1:ngrid, findInterval(mm[, :

bg = NA, pch = par("pch"), cex = 1, ...)
{
if (is.null(bandwidth))
bandwidth <- range(x) * span/3
s <- svysmooth(y ~ x, design = design, bandwidth = bandwidth)
points(x, y, pch = pch, bg = bg, col = col)
lines(s[[1]], col = col.smooth, ...)
