Work on lists of datasets instead of individual datasets by using functional programming
Analyzing a lot of datasets can be tedious. In my work, I often have to compute descriptive statistics, or plot some graphs for some variables for a lot of datasets. The variables in question have the same name accross the datasets but are measured for different years. As an example, imagine you have this situation: data2000 <- mtcars data2001 <-...

Lesser known dplyr tricks
In this blog post I share some lesser-known (at least I believe they are) tricks that use mainly functions from dplyr. Removing unneeded columns Did you know that you can use - in front of a column name to remove it from a data frame? mtcars %>% select(-disp) %>% head() ## mpg cyl hp drat wt qsec vs am gear car...

Lesser known purrr tricks
purrr is a package that extends R’s functional programming capabilities. It brings a lot of new stuff to the table and in this post I show you some of the most useful (at least to me) functions included in purrr. Getting rid of loops with map() library(purrr) numbers <- list(11, 12, 13, 14) map_dbl(numbers, sqrt) ## [1] 3.316625 3.464102 3....
