## Bar chart in r

You’ve probably seen bar plots where each point on the x-axis has more than one bar. The image below shows an example. The bar plot shows the frequency of eye color for four hair colors in 313 female students. The data is from the HairEyeColor data set. This type of plot is called a grouped bar plot. beside=T tells R to plot the bars, well, beside each other. (Try it without this argument and watch what happens.) ylim insures that no bar will rise above the highest value on the y-axis. col=color.names supplies the colors named in the vector.

R Bar Chart Syntax. H is a vector or matrix containing numeric values used in bar chart. A simple R Bar chart: A simple bar chart is created using just the input vector and the name R Bar Chart with Labels, Title and Colours. Horizontal R Bar chart: Stacked bar chart in R: Grouped bar chart Let’s create a simple bar chart in R using the barplot() command, which is easy to use. First, we set up a vector of numbers. Then we count them using the table() command, and then we plot them. The table() command creates a simple table of counts of the elements in a data set. H <- c(2,3,3,3,4,5,5,5,5,6) Introduction to ggplot Before diving into the ggplot code to create a bar chart in R, I first want to briefly explain ggplot and why I think it's the best choice for graphing in R. ggplot is a package for creating graphs in R, but it's also a method of thinking about and decomposing complex graphs into logical subunits. ggplot takes each Bar Charts in R How to make a bar chart in R. Examples of grouped, stacked, overlaid, and colored bar charts. In R there are multiple ways for creating graphs, including the base graphics, lattice graphics and the ggplot2 grammar of graphics approach. To illustrate how we can create a bar chart using these packages we will make use of some data taken from the FAO statistics website for the UK in 2007. The data is for production (in metric tonnes) of Bar plots can be created in R using the barplot () function. We can supply a vector or matrix to this function. If we supply a vector, the plot will have bars with their heights equal to the elements in the vector. Let us suppose, we have a vector of maximum temperatures (in degree Celsius) for seven days as follows. You’ve probably seen bar plots where each point on the x-axis has more than one bar. The image below shows an example. The bar plot shows the frequency of eye color for four hair colors in 313 female students. The data is from the HairEyeColor data set. This type of plot is called a grouped bar plot.

## Obviously, the labelling of the bars is hopeless here. We could rotate them by 90 degrees, and then all the countries should fit, but a horizontal bar plot may look

Stacked bar charts are another form of bar charts used to compare values across categories. As the name implies, the bars for each category are stacked on top  lattice::barchart() from the lattice package makes bar graphs from pre-tabulated data. Raw data can be tabulated using xtabs(), but the syntax is unusual  25 Jan 2019 1st- normal bar chart (with a diverging aspect) using the gapminder dataset. 2nd- divergent bars using the starwars dataset from dplyr package.
