Fortunately, the mean function comes with the na.rm (i.e. NA remove) option, which can be used to ignore NA values. Let’s do this in practice: mean (x2, na.rm = TRUE) # Use na.rm option # 4.625 More count by group options. There are other useful ways to group and count in R, including base R, dplyr, and data.table.

Other functions remove NA's before calculations (as na.rm = TRUE in base R functions). Function criterion should return logical vector of same size and shape as its argument. This function will be applied to each column of supplied data and TRUE results will be used. spark_tbl %>% summarise_all(~sum(as.integer(is.na(.)))) You'd need the as.integer() in there since Spark doesn't convert logical values to numeric implicitly like with base R sum() or mean(). For now you can do something like the following workaround: Se hela listan på towardsdatascience.com First, if we want to exclude missing values from mathematical operations use the na.rm = TRUE argument. If you do not exclude these values most functions will return an NA . # A vector with missing values x <- c ( 1 : 4 , NA , 6 : 7 , NA ) # including NA values will produce an NA output mean ( x ) ## [1] NA # excluding NA values will calculate the mathematical operation for all non-missing So the best solution to count TRUE values is to use the sum() function along with the na.rm argument as TRUE.
