R is.na Function Example (remove, replace, count, if else, is not NA) Well, I guess it goes without saying that NA values decrease the quality of our data. Fortunately, the R programming language provides us with a function that helps us to deal with such missing data: the is.na function. In the following article, Im going to explain what the function does and how the function can be. R's binary and logical operators will look very familiar to programmers. Check if Object is NULL in R. Consider the following example vector in R: x1. Description
NULL represents the null object in R : it is a reserved word. NULL is often returned by expressions and functions whose value is undefined. Usage Arguments
an object to be tested or coerced.
ignored. Value
as.null ignores its argument and returns NULL . Not In Ruby
is.null returns TRUE if its argument's value is NULL and FALSE otherwise. Details
NULL can be indexed (see Extract) in just about any syntactically legal way: whether it makes sense or not, the result is always NULL . Objects with value NULL can be changed by replacement operators and will be coerced to the type of the right-hand side. Not In Regs
NULL is also used as the empty pairlist: see the examples. Because pairlists are often promoted to lists, you may encounter NULL being promoted to an empty list.
Objects with value NULL cannot have attributes as there is only one null object: attempts to assign them are either an error ( attr ) or promote the object to an empty list with attribute(s) ( attributes and structure ). References

R operator in is handy for work with vectors, but how to use it oppositely? Something like notin that will exclude anything that is in a vector.
For example, you have 2 data frames. You would like to select rows from the second data frame matching with ids in the first one. R in operator
Maybe someone will do left_join from dplyr and after then filter, but it is not necessary by using a vector with ids. As you see, with the operator in, it is done easily. R not in operator, opposite to in Ms Access Not Equal Operator
here is not actual not in operator. It is done by using negation (NOT operator) like this.
You can test how it looks in separate columns. Whats next?
Check out my favorite RStudio tips and tricks. For example, how to comment out multiple lines of R script at once.
