What does the plot function in R do?
The plot() function in R isn’t a single defined function but a placeholder for a family of related functions. The exact function being called will depend upon the parameters used. At its simplest, plot() function simply plots two vectors against each other. This gives a simple plot for y = x^2.
What does plot mean in Rstudio?
Plot of means and interaction plots. Means or medians for a group can be plotted with error bars showing standard deviation, standard error, or confidence interval for the statistic. For two-way data, these plots are sometimes called interaction plots.
Which R function is used to plot a file?

What is a means plot?
Mean plots are used to see if the mean varies between different groups of the data. For example, a data series with 400 points can be divided into 10 groups of 40 points each. A mean plot can then be generated with these groups to see if the mean is increasing or decreasing over time.
