R Markdown

This is an R Markdown document. Markdown is a simple formatting syntax for authoring HTML, PDF, and MS Word documents. For more details on using R Markdown see http://rmarkdown.rstudio.com.

When you click the Knit button a document will be generated that includes both content as well as the output of any embedded R code chunks within the document. You can embed an R code chunk like this:

Loading the necessary libraries and defining varibles

library(tb346a2)
library(dplyr)
library(tidyr)
library(ggplot2)

set.seed(1)
t1 <- tibble(v1 = paste0("G", 1:10), v2 = runif(10,min = 75, max = 125))
t1

t2 <- tibble(v1 = paste0("G", 1:15),  v3 = sample(LETTERS[1:6],size= 15, replace = TRUE))
t2

t3 <- tibble(v1 = paste0("G", 1:20),  v4 = rnorm(20,mean = 100, sd = 20))

Let's joini t1, t2, and t3 within a single pipeline, using:

• left_join
• right_join
• full_join
• inner_join

left_join(t1, t2) %>% left_join(., t3)

right_join(t1, t2) %>% right_join(., t3)

full_join(t1, t2) %>% full_join(., t3)

inner_join(t1, t2) %>% inner_join(., t3)

Using lapply to read in csv files from the package extdata/ folder

a <- dir(system.file("extdata/", package = "geospaar"), pattern = "FAOSTAT", 
          full.names = TRUE)

crops <- lapply(a, readr::read_csv)

Including Plots

You can also embed plots, for example:

plot(pressure)

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.
