In R, missing values are represented by the symbol NA (not available). Impossible values (domain errors like division by 0 et logs of negative numbers are represented by the symbol NaN (Not-A-Number). NA is used for both numeric and string data.. R being a programming environment, there is no global way to deal with missing values.

This high average value is despite the exclusion of a large number of R2: R-squared - Coefficient of determination. M-1, 50.1, NA, 82.28, 17.72, 0.18, NA.

If ordered is TRUE, the factor levels are assumed to be ordered.For compatibility with S there is also a function ordered.. is.factor, is.ordered, as.factor and as.ordered are the membership and coercion functions for these classes. foo <- read.table(file="Your_file.txt", na.strings=c("", "NA"), sep="\t") # if your file is tab delimited If you have already your table loaded, you can act as follows: foo[foo==""] <- NA Then to keep only rows with no NA you may just use na.omit(): foo <- na.omit(foo) Or to keep columns with no NA: foo <- foo[, colSums(is.na(foo)) == 0] We can exclude missing values in a couple different ways. First, if we want to exclude missing values from mathematical operations use the na.rm = TRUEargument. If you do not exclude these values most functions will return an NA.

Creating sample dataframe that includes missing values na.exclude differs from na.omit only in the class of the "na.action" attribute of the result, which is "exclude". The only benefit of na.exclude over na.omit is that the former will retain the original number of rows in the data.

The codes of a factor may contain NA. Now it is possible to find NA values by running the code to check each value, but unless you have a special need for this is.na() function will do the job. is.na R. Using is.na R to check for NA in R is quite simple. The is.na() function has the form of is.na(dataset), and it returns true data point with an NA value pause for all others.

Exclude Missing Values (NA) The na.omit () method from the dplyr library is a simple way to exclude missing observation. Dropping all the NA from the data is easy but it does not mean it is the most elegant solution. During analysis, it is wise to use variety of methods to deal with missing values
