approxfun returning value higher than I would expect
Below is the code that I am using in a much larger function. I would
expect a bankfull measure at zero to be between 0.6 and 0.8 approxfun
is returning 0.8136986. I am sure that I am missing something.
measure_bkf <- (structure(list(measurment_num = c(0, 0.2, 0.4, 0.6,
0.8, 1, 1.2,
1.4, 1.6, 1.8, 2, 2.2, 2.4, 2.6, 2.8, 3, 3.2, 3.4), bankfull_depths_m
= c(-0.48,
-0.48, -0.42, -0.26, 0.58, 0.48, 0.47, 0.54, 0.5, 0.52, 0.52,
0.56, 0.58, 0.61, 0.68, 0.62, 0.67, 0.66)), .Names = c("measurment_num",

NA preserved in logical call - I don't understand this behavior because NA is not equal to 0
...havior of the below piece of code. The NAs are
making it past the logical call ==0. I am sure that I am missing
something. I just don't understand this behavior. Thanks for your
help in advance.
