dplyr great , fast library.

using %.% operator enables powerful manipulation.

in first step, need limit output 500 rows max (for display purposes).

how can that?

par<-filter(pc,child_concept_gid==as.character(mcode)) %>% select(parent_concept_gid)

what need like

filter(pc,condition,rows=500)

is there direct way or nice workaround without making first step separate step (outside %>% "stream")

to limit output of filter, 1 can add together after filter function

top_n()

credit goes commenter joran

solution

par<-filter(pc,child_concept_gid==as.character(mcode)) %>% top_n(500) %>% select(parent_concept_gid)

r dplyr
