# NOT RUN { x <- sample(c(1:10, NA), 30, replace = TRUE) na.count(x) x.df <- do.call(data.frame, lapply(1:4, function(i) sample(c(1:10, NA), 30, replace = TRUE))) colnames(x.df) <- paste("X", 1:4, sep = "") na.count(x.df) # }

If we want to count the number of NA values in our example vector, we can use a combination of the sum and is.na functions: sum (is.na( vec)) # 3. sum (is.na (vec)) # 3. After running the previous code, the RStudio console returns the value 3, i.e. our example vector contains 3 NA values.

I keep expecting R to have something analogous to the =count function in Excel, but I can't find anything. I simply want to count the data for a given category. I've been using the ddply() function in the plyr package to summarize means and st dev of my data, with this code: ddply(NZ_Conifers,.(ElevCat, DataSource, SizeClass), summarise, avgDensity=mean(Density), sdDensity=sd(Density), n=sum Dear Jim (25 minutes!), Richard (27 minutes!), and Chuck, Thanks to your hints, I have come up with what I hope is a pithy idiom that drops columns of a dataframe (df) in which the number of NAs is > (e.g.) 30. tmp <- df tmp <- tmp[, which(as.numeric(colSums(is.na(tmp))) > 30)] df <- tmp I wonder if we have a place to keep R programming idioms (which probably get unnecessarily reinvented). Dealing with Missing Values. A common task in data analysis is dealing with missing values. In R, missing values are often represented by NA or some other value that represents missing values (i.e.

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've been using the ddply() function in the plyr package to summarize means and st dev of my data, with this code: ddply(NZ_Conifers,.(ElevCat, DataSource, SizeClass), summarise, avgDensity=mean(Density), sdDensity=sd(Density), n=sum To count the data after omitting the NA, use the same tools, but wrap dataset in na.omit(): > NROW(na.omit(dataset)) [1] 993 The difference between NROW() and NCOL() and their lowercase variants ( ncol() and nrow() ) is that the lowercase versions will only work for objects that have dimensions (arrays, matrices, data frames). A common task in data analysis is dealing with missing values. In R, missing values are often represented by NA or some other value that represents missing values (i.e. 99).

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()). count() is paired with tally(), a lower-level helper that is equivalent to df %>% summarise(n = n()). Supply wt to perform weighted counts, switching the summary from n = n() to n = sum(wt). add_count() and add_tally() are
