Promoted by John Tukey, exploratory data analysis focuses on exploring data to understand the data’s underlying structure and variables, to develop intuition about the data set, to consider how that data set came into existence, and to decide how it can be investigated with more formal statistical methods.” “Exploratory data analysis is an approach for summarizing and visualizing the important characteristics of a data set. The more factors you have, the more difficult it is to come up with a single (meaningful) plot that gives you a useful view into the data. Plots can also be very helpful in assumption checking. I make A LOT of plots when I get a dataset. In my experience, plots are crucial in learning about your data.

Note that you need to be careful to ensure that all relevant files for the analysis have been committed to Git prior to generating the results (you can use wflow_publish or wflow_git_commit).

#R MULTIPANEL PLOTS EPS CODE#
Tracking code development and connecting the code version to the results is critical for reproducibility. The numbers assigned to fig were arrived at with a hit-and-trial method to achieve the best looking plot.Great! You are using Git for version control. Note: we have used parameters cex to decrease the size of labels and mai to define margins. For example, the whole plot area would be c(0, 1, 0, 1) with (x1, y1) = (0, 0) being the lower-left corner and (x2, y2) = (1, 1) being the upper-right corner. We need to provide the coordinates in a normalized form as c(x1, x2, y1, y2). The graphical parameter fig lets us control the location of a figure precisely in a plot. Note that only the ordering of the subplot is different. Same plot with the change par(mfcol = c(2, 2)) would look as follows. The only difference between the two is that, mfrow fills in the subplot region row wise while mfcol fills it column wise. This same phenomenon can be achieved with the graphical parameter mfcol. Par(mfrow=c(1,2)) # set the plotting area into a 1*2 array For example, if we need to plot two graphs side by side, we would have m=1 and n=2. It takes in a vector of form c(m, n) which divides the given plot into m*n array of subplots. Graphical parameter mfrow can be used to specify the number of subplot we need. Here we will focus on those which help us in creating subplots. You will see a long list of parameters and to know what each does you can check the help section ?par. For example, you can look at all the parameters and their value by calling the function without any argument. The par() function helps us in setting or inquiring about these parameters. R programming has a lot of graphical parameters which control the way our graphs are displayed.
We can put multiple graphs in a single plot by setting some graphical parameters with the help of par() function. Sometimes we need to put two or more graphs in a single plot.
