string transformation in R

Navigation
3

I would like to know if I can make a remark about a string variable in upper case.

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"

Is there a way to start a Select (SQL) in the middle of the data table? Deselect all checkboxes when returning to the previous page
