Remove Rows with NA using na.omit () In this method, we will use na.omit () to delete rows that contain some NA values. Syntax: # Syntax na.omit (df) is the input data frame. In this example, we will apply to drop rows with some NA’s. It will drop rows with na value / nan values. This is the fastest way to remove na rows in the R programming language. # remove na in r - remove rows - na.omit function / option ompleterecords <- na.omit(datacollected) Passing your data frame or matrix through the na.omit() function is a simple way to purge incomplete records from your analysis ...We can use the following code to remove the first row from the data frame: #remove first row df <- df [-1, ] #view updated data frame df team points assists rebounds 2 A 99 33 30 3 B 90 28 28 4 C 86 31 24 5 D 88 39 24 6 E 95 34 28..
