However, there's a bug in that function such that the na.action parameter does not work.I asked for help on stackoverflow; two users there offered two different ways of dealing with NA values. However, the problem with both solutions is that when there is an NA value, that row is dropped and not considered in.

In R, missing values are often represented by NA or some other value that represents missing values (i.e. 99).We can easily work with missing values and in this section you will learn how to:

    x: an object from which to drop unused factor levels. exclude: passed to factor(); factor levels which should be excluded from the result even if present.Note that this was implicitly NA in R <= 3.3.1 which did drop NA levels even when present in x, contrary to the documentation.The current default is compatible with x[ , drop=TRUE].. further arguments passed to methods How R does indexing. Every time R shows you a vector, it displays a number such as [1] in front of the output. In this example, [1] tells you where the first position in your vector is. This number is called the index of that value. If you make a longer vector — say, with the numbers from 1 …

    For missing values that lie outside the 1.5 * IQR limits, we could cap it by replacing those observations outside the lower limit with the value of 5th %ile and those that lie above the upper limit, with the value of 95th %ile. Below is a sample code that achieves this. How to omit NA values in the final plot when plotting a SpatialPolygonsDataFrame in R? Ask Question Asked 3 years, 3 months ago.
