You can also embed plots, for example:
##
## Attaching package: 'dplyr'
## The following objects are masked from 'package:stats':
##
## filter, lag
## The following objects are masked from 'package:base':
##
## intersect, setdiff, setequal, union
Note that the echo = FALSE parameter was added to the
code chunk to prevent printing of the R code that generated the
plot.
