I wonder if I can turn an observation of a variable, which has a string shape, into uppercase letters.

for example:

#como esta:
x=c("Casa branca","Barco Azul","casa preta")
> x
[1] "Casa branca" "Barco Azul"  "casa preta"
#como ficaria:
[1] "CASA BRANCA" "BARCO AZUL"  "CASA PRETA"

x <- c("Casa Branca", "Barco Azul", "Casa Preta")
toupper(x)
[1] "CASA BRANCA" "BARCO AZUL"   "CASA PRETA"
