barplot(values)# Basic barchart in R Figure 1: Basic Barchart in R Programming Language. Figure 1 shows the output of the previous R code: A barchart with five bars. However, you can also see that our basic barchart is very plain and simple. In the next examples, I’ll show you h...
"r"(regular)首先会对数值范围向两端各延伸4%,然后在延伸后的数值区间中设置坐标值;"i"(internal)直接在原始的数据范围中设置坐标值;**"s"(standard)和"e"(extended)、;"d"(direct)目前还不支持。** dotchart(t(VADeaths),xlim = c(0,100),main = "Death Rates in Virginia-1940", lcolor = 'sky...
As you can see, the previous R code has returned the “Error in barplot.default(data) : ‘height’ must be a vector or a matrix”. The reason for this is that we have inserted a data.frame object into the barplot function, i.e. we have specified the height to be equal to our da...
In the R code above, we used the argumentstat = “identity”to make barplots. Note that, the default value of the argumentstatis“bin”. In this case, the height of the bar represents the count of cases in each category. To make a barplot of counts, we will use themtcarsdata set...
An R script is available in the next section to install the package. The aim of this tutorial is to show you step by step, how to plot and customize a bar chart using ggplot2.barplot function. At the end of this document you will be able to draw, with few R code, the following ...
A grouped barplot display a numeric value for a set of entities split in groups and subgroups. Before trying to build one, check how to make abasic barplotwithRandggplot2. A few explanation about the code below: input dataset must provide 3 columns: the numeric value (value), and 2 categ...

Code Interactive mekko chart A Mekko chart, also known as a Marimekko chart, is atwo-dimensional stacked bar chartwhere both the height and width of each bar segment represent different data dimensions, making it useful for visualizing categorical data distributions and market share comparisons. ...
This article describes how to easily createbarplotswitherror bars in Rusing theggpubrpackage, an extension of ggplot2 for creating publication ready plots. The following R code produces barplots showing means +/- sd and the jittered data points for each group. ...
Please note that a similar R code could also be applied to other types of ggplot2 graphics such as line plots or histograms. If you have additional questions, don’t hesitate to let me know in the comments section.
