2017_SISBID_3_05_bigjobs_activity1_spin.R

#' This is an illustration of an R script that can be treated like an
#' RMarkdown document using `knitr::spin()`.
#'
#' To compile the document, use
#'
#'     knitr::spin("2017_SISBID_3_05_bigjobs_activity1_spin.R")
#'
#' This will create the result `2017_SISBID_3_05_bigjobs_activity1_spin.html`.
#'
#' Let's first load some libraries. Note that I use `#+` with some
#' chunk options.

#+ warning=FALSE, message=FALSE
library(babynames)
library(dplyr)
library(ggplot2)

#' Now let's grab the cases of "Karl" or "Carl" (and males only) from
#' the `babynames` dataset.

karl <- babynames %>%
    filter(name=="Karl" | name=="Carl", sex=="M")

#' Now let's make a plot. I'll again use chunk options to adjust the size.

#+ fig.width=12, fig.height=8
karl %>% ggplot(aes(x=year, y=prop, color=name)) + geom_line()
