It’s TRUE where variable is number else FALSE. Value. If arr.ind == FALSE (the default), an integer vector, or a double vector if x is a long vector, with length equal to sum(x), i.e., to the number of TRUEs in x.. Basically, the result is (1:length(x))[x] in typical cases; more generally, including when x has NA's, which(x) is seq_along(x)[!is.na(x) & x] plus names when x has.. If arr.ind == TRUE and x is an array (has a dim attribute 2015-07-28 Example of Subset () function in R with select option: # subset () function in R with select specific columns newdata<-subset (mtcars,mpg>=30, select=c (mpg,cyl,gear)) newdata. Above code selects cars, mpg, cyl, gear from mtcars table where mpg >=30 so the output will be. The function n() returns the number of observations in a current group.

R select function

One or more unquoted expressions separated by commas. You can treat variable names like they are positions. Positive values select variables; negative values to drop variables. If the first expression is negative, select () will automatically start with all variables. Use named arguments to rename selected … - `select(df, A, B ,C)`: Select the variables A, B and C from df dataset. - `select(df, A:C)`: Select all variables from A to C from df dataset.

Give the TRUE indices of a logical object, allowing for array indices. The grepl R function searches for matches of certain character pattern in a vector of character strings and returns a logical vector indicating which elements of the vector contained a match. In the following R programming tutorial , I’ll explain in three examples how to apply grep, grepl, and similar functions in R. Well, the subset() function in R is used to subset the data from it’s parent data. i.e.

It’s possible to select either n random rows with the function sample_n() or a random fraction of rows with sample_frac(). We first use the function set.seed() to initiate random number generator engine. This important for users to reproduce the analysis. select.Rd.

This example shows a simple user-defined R function, which computes the sum of the two input values x and y. The last row of code shows how to use the return command in R. We simply need to insert the desired output of our function between the parentheses of the return command: We use the select function to tell R what variables or columns of our data set we want to keep. We will practice using the select function using the starwars dataset that comes with the dplyr package.
