Dear R users,
This works as expected:
• plot(density(c(1,2, 3, 4, 5, NA), na.rm=TRUE))
This raises an error
• plot(density(c(1,2, 3, 4, 5, NA), na.rm=TRUE, weights=c(1, 1, 1, 1, 1, 1)))
• plot(density(c(1,2, 3, 4, 5, NA), na.rm=TRUE, weights=c(1, 1, 1, 1, 1, NA)))
This seems to work (it triggers a warning that the weights don’t add up to 1,
which makes sense*):
• plot(density(c(1,2, 3, 4, 5, NA), na.rm=TRUE, weights=c(1, 1, 1, 1, 1)))
Questions
• But shouldn’t the na.rm filter also filter the corresponding weights?
• Extra question: In case the na.rm filter is changed to filter the weights,
the check for sum(weights) == 1 might trigger false positive warnings since the
weights might not add up to 1 anymore
Best wishes,
Matthias
