I wish to write "" using paste(), but
paste("\"","Hola","\"",sep="")
[1] "\"Hola\""
while the same approach works with ''
paste("\'","Hola","\'",sep="")
[1] "'Hola'"
why this difference? how could I do it to get "Hola" ?
I need this to write this string in R:
v.extract codigo_Montseny07_clump out=extract11917 where="(GRIDCODE =
11917)"
and pass it to grass. Something like:
for (i in polis){
system("g.region vect=codigo_Montseny07_clump")
nomextract <- paste("extract",i,sep="")
grcomm <- paste("v.extract codigo_Montseny07_clump out=",nomextract,
" where=\"(GRIDCODE = ",i,")\" ",sep="")
system(grcomm)
...
Thanks
Agus
