I am working with the "rugratrace.csv$"$ data frame in Canvas. I decide I would like to understand how time spent on chores has changed over time, separately by sex. In order to do this, I run the following lines of code:

chores$\_$by$\_$sex $<-$ rr $\%>\%$ group$\_$by$($dataset$,$sex$)\%>\%$

summarize$($meanchores $=$ mean$($chores$,$na$.$rm$=$T$))$

But I get the error:

error$1.$png

What is the reason for this error?

I need to assign $\%>\%$ a value so that it is in the global environment
