rpdo

rpdo has been superseded by the rsoi package which includes the historical and most recent monthly PDO index values together with related climate indices.

rpdo is an R data package of monthly Pacific Decadal Oscillation (PDO) index values from January 1900 to September 2018.

The function pdo_download() scrapes the data from the no longer updated http://research.jisao.washington.edu/pdo/PDO.latest.

Demonstration

library(rpdo)
#> rpdo has been superseded by rsoi
library(ggplot2)

data <- rpdo::pdo

data <- subset(data, data$Month == 1)

ggplot(data = data, aes(x = Year, y = PDO)) +
  geom_smooth(span = 0.1, se = FALSE, color = "black", method = "loess") +
  geom_point() +
  ylab("January PDO Index")
#> `geom_smooth()` using formula = 'y ~ x'
