## How do I replace all with NA in R?

The classic way to replace NAs in R is by using the IS.NA() function. The IS.NA() function takes a vector or data frame as input and returns a logical object that indicates whether a value is missing (TRUE or VALUE). Next, you can use this logical object to create a subset of the missing values and assign them a zero.

## How do you replace values in a vector with Na?

If na is a named list and as. tag FALSE , it is possible to replace different multiple values by NA for different variables separately. For example, set_na(x, na list(v1 c(1, 4), v2 5:7)) would replace all 1 and 4 in v1 with NA and all 5 to 7 in v2 with NA .

## How do I remove all rows in R?

To remove the rows in R, use the subsetting in R. There is no built-in function of removing a row from the data frame, but you can access a data frame without some rows specified by the negative index. This process is also called subsetting. This way, you can remove unwanted rows from the data frame.

## How do I exclude data with NA in R?
