[R] ggplot2: 'not finding <-<- error'

[Chris Evans]

I think it's your xlab.  Should be:

### creating reproducible example
library(tidyverse)

rnorm(50) %>%
  as_tibble() %>%
  rename(cfs = value) -> pdx_disc


ggplot(data = pdx_disc, aes(x = NULL, y = cfs)) +
  geom_boxplot(
    # custom boxes
    color='#00008B',
    fill='#00008B',
    alpha=0.2,
    # custom outliers
    outlier.color='#B22222',
    outlier.fill='#FF3030',
    outlier.size=2) +
  coord_flip() +
  ### I think this is what you want for your xlab:
  xlab('Portland Discharge')
