Dummies has always stood for taking on complex concepts and making them easy to understand. Dummies helps everyone be more knowledgeable and confident in applying what they know. Null values have no notion of equality in R. Therefore, NA == NA just returns NA. In fact, NA compared to any object in R will return NA. The filter statement in dplyr requires a boolean argument, so when it is iterating through col1, checking for inequality with filter(col1 != NA), the 'col1 != NA' command is continually throwing NA values for each row of col1. You can manually filter out the "NA" rows as shown below but it would be far better to read the data in cleanly in the first place.

In this article we will work on learning how to remove columns from data frame in R using select() command.. Theory. It is often the case, when importing data into R, that our data frame of interest will have a large number of columns.. But assume we only need some of them for our statistical analysis.. One way to go around this problem is to select (keep) the columns we need.
In this example, we will create a data frame with some of the rows containing NAs. > DF1 = data.frame(x = c(9, NA, 7, 4), y = c(4, NA, NA, 21)) > DF1 x y 1 9 4 2 NA NA 3 7 NA 4 4 21. In the second row we have all the column values as NA. 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, I’m going to explain what the function does and how the function can be Is there any way to remove NA values from a vector?
