You could do it this way: x1 <- c ( "Dec", "Apr", "Jan", "Mar") This creates a vector of strings (it’s not a factor ). But there are some risks. There’s no check on typos. x_typo <- c ( "Dec", "Apr", "Jam", "Mar" ) x_typo

For even more complicated criteria, use case_when (). recode () is a vectorised version of switch (): you can replace numeric values based on their position or their name, and character or factor values only by their name.
Splet07. feb. 2024 · create some sort of distribution plot (boxplot, violin plot) with all of the ages shown discretely on the x axis. you can examine that to see if there are shifts in the mean, or in the variance. that would give you some idea on what kind of bins you could try. Then you can just try it out both ways.
SpletThe factor () command is used to create and modify factors in R: sex <- factor(c("male", "female", "female", "male")) R will assign 1 to the level "female" and 2 to the level "male" (because f comes before m, even though the first element in this vector is "male" ). emily gerard leighSpletThe previous output of the RStudio console shows the structure of our example data: It’s a factor vector consisting of eight vector elements. Note that our factor has four different factor levels – A, B, C, and D. The factor level D is empty.
