Answer 1

Not a complete solution, but the essence.

library(tidyverse)
library(ggplot2)

df <- tibble(
  type = c("barley",
           "maize",
           "sunlower oil",
           "wheat"),
  ukraine = c(0.974, 0.1643, 0.4221, 0.0891),
  russia = c(0.095, 0.0160, 0.2140, 0.1420)
)

# A tibble: 4 x 3
  type         ukraine russia
  <chr>          <dbl>  <dbl>
1 barley        0.974   0.095
2 maize         0.164   0.016
3 sunlower oil  0.422   0.214
4 wheat         0.0891  0.142

df %>%  
  gather(-type, key = "country", value = "value") %>%  
  ggplot() + 
  aes(x = type, y = value, fill = country) + 
  geom_col() + 
  coord_flip() 

Answer 2

ggplot2 is basically used to create elegant data visualization using graphics.

Here is example:

library(ggplots2) 
ggplot2(dataset, aes(x='dataset_col1', y='dataset_col2')

here we get output of dataset_col1 (x axis) and dataset_col2(y-axis)

Before running this code, you need to download the package -> ggplot2 from the packages
