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. 2021-3-4 · How to remove rows in a data.table object with NA's in R?

You can access your options with getOption("na.action") or options("na.action") and you can set it with, for example, options(na.action = "na.omit") However, from the R output you provide in example 1, it seems that you are setting na.action = na.omit. In R, you can change the NA values to a value to visualize where these NA values are and what could be going on with your data. If you choose, you could also remove them.

It is an efficient way to remove na values in r. complete.cases () – returns vector of rows with na values # remove na in r – remove rows – na.omit function / option. Ompleterecords<- na.omit(datacollected) Passing the data frame by the na.omit()function is the easiest way for purging the records of incomplete ones from your analysis. It is the most efficient way of removing the na values in r. complete.cases() -returns factor of roes with na values The previous R code takes a subset of our original vector by retaining only values that are not NA, i.e.
