您可以覆盖％+％运算符以具有更好的字符串隐含语法：

'%+%' <- function(x,y) paste(x,y,sep="")

y<-"y1"
x<-"somethingorother"
query<-
'SELECT DISTINCT x AS ' %+% x %+%',\n'    %+%
'                y AS ' %+% y %+% '\n'    %+%
' FROM tbl
 WHERE id=%s
 AND num=%d'

cat(query,"\n")

产量：

> cat(query,"\n")
SELECT DISTINCT x AS somethingorother,
                y AS y1
 FROM tbl
 WHERE id=%s
 AND num=%d
