%strict>%

%G>%

uses tibble::glimpse on the output

%D>%

debugs the pipe chain at the relevant step

%C>%

Examples

# silence a warning
data.frame(a= c(1,-1)) %W>% transform(a=sqrt(a))

# view stepps of chain in the viewer
iris %V>% head(2) %V>% `[`(4:5)

# log steps in the console
iris %L>% {Sys.sleep(1);head(.,2)} %L>% {Sys.sleep(2);.[4:5]}

# use print, summary or glimpse on output
iris %P>% head(2) %P>% `[`(4:5)
iris %S>% head(2) %S>% `[`(4:5)
iris %G>% head(2) %G>% `[`(4:5)

# debug the chain
iris %>% head(2) %D>% `[`(4:5)
