How to mutate a year quarter str into date?

Question

I have a df that comes from an api with a Trimestre (Código) column in string format:

pib$`Trimestre (Código)` <- c(199101,199102,199103,199104,199201,199202,...)

but i need to mutate this column into date format. I have tried the folowing:

> 
> pib %>% 
> mutate(date = parse_date(`Trimestre (Código)`, format='%Y%q')) %>%
> select('Trimestre (Código)', "Setores e subsetores", Valor) %>%
> pivot_wider(names_from = "Setores e subsetores",
> values_from = Valor)

but I just receive the error 'unsupported format %q'. How to do it?

Answer 1

library(lubridate)
library(dplyr)

pib <- data.frame(Trimestre = c(199101,199102,199103,199104,199201,199202))

pib %>%
  mutate(date = yq(Trimestre))
