I am trying to replicate among the instances in the dplyr bundle however am obtaining this mistake message. I am anticipating to see a brand-new column n generated with the regularity of each mix. What am I missing out on? I triple inspected that the bundle is filled.

collection(dplyr)# sum up remove a solitary layer of groupingby_vs_am Mistake in n(): This feature needs to not be called straight

* I assume you have dplyr and also plyr filled in the exact same session.

dplyr is not plyr. ddply is not a feature in the dplyr bundle.

Both dplyr as well as plyr have the features summarise/summarize. Consider the outcomes of problems ()to see covered up items. As discussed by the previous solution, you might have a problem in between plyr and also dplyr. You can to run this command to discharge the plyr plan. remove ("plan: plyr", discharge =REAL)Then you can proceed as expected.library (dplyr)... summarise(n=n() ) To prevent complications with concealing features, it is clear to make use of the"
bundle:: feature" spec, like instance listed below: hold-up In an additional instance, this mistake happened in

the complying with code.library (dplyr) # dplyr 0.5.0 collection(lazyeval) df% group_by _ (g)%>

%sum up _(n= n (), amount =interp(~ amount(col, na.rm =REAL), col = as.name(g)))# Mistake in n(): This feature should not be called directlyIt can be fixed as follows.df%> %group_by _(g) %>%sum up _( n= "n()", amount =interp(

~ amount(col, na.rm = REAL), col = as.name(g))) # A tibble: 3 × 3 # team n amount # # 1 1 1 1 # 2 2 2 4 # 3 3 3 9
Dealt with comparable concern while carrying out code according to discussed blog site and afterwards run service in detach("bundle: plyr", discharge=REAL)

Caution message:' plyr 'namespace can not be unloaded:
