My question involves summing up values across multiple columns of a data frame and creating a new column corresponding to this summation using dplyr Thus, after the summarise, the last grouping variable specified in group_by, 'gear', is peeled off

Ddply() from plyr is working. Is there a way to instruct dplyr to use summarise_each with na.rm=true I would like to take the mean of variables with summarise_each(mean) but i don't know how to specify it to ignore missing v.
