Search everywhere only in this topic Advanced Search. Hello, I have a table with 2947 rows and 1 column containing only integer values in the range 1 to 30. I want to calculate the number of distinct values in that column. I used the … Removing rows with NA from R dataframe. At this point, our problem is outlined, we covered the theory and the function we will use, and we are all ready and equipped to do some applied examples of removing rows with NA in R. Recall our dataset.

sum(is.na(airquality)) # [1] 44 You can look at the total number of NA values per row or column: head(rowSums(is.na(airquality))) # [1] 0 0 0 0 2 1 colSums(is.na(airquality)) # Ozone Solar.R Wind Temp Month Day 37 7 0 0 0 0 You can count the NAs in each row with this command: rowSums(is.na(dat)) where dat is the name of your data frame. Count NAs via sum & colSums Combined with the R function sum, we can count the amount of NAs in our columns. According to our previous data generation, it should be approximately 20% in x_num, 30% in x_fac, and 5% in x_cha. 1.If you need to find out which columns you are having na just give the code as colnames(is.na(data_name)) 2.If you need to find out how many na’s are there in the whole dataset sum(is.na(data_name)) 3.If you need to find how many columns are having na’s (Viewing only NA Data from Dataset) nrow(data_set[!complete.cases(data_set),]) Counts NAs in an object.

When counting the occurence of distinct values, it gives you new information about the data set. Furthermore, when you count occurances among multiple columns it can show relationships between columns that you would not see simply by looking at the raw numbers. Count Number of Cases within Each Group of Data Frame; Count Number of Rows by Group Using dplyr Package; Count NA Values in R; Count Unique Values in R; The R Programming Language . In summary: In this tutorial you learned how to return the amount of unique values by group in the R programming language. If you have any further questions, let count.Rd. count () lets you quickly count the unique values of one or more variables: df %>% count (a, b) is roughly equivalent to df %>% group_by (a, b) %>% summarise (n = n ()) .
