Method 1: Using plot.new() The plot. new() function will create the empty plot. This will give a signal to R that a new window of the plot is created. So, an empty window of the plot is created with the help of this function.
The reason your plot is blank is that matplotlib didn't auto-adjust the axis according to the range of your patches. Usually, it will do the auto-adjust jobs with some main plot functions, such as plt. plot(), plt.
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.
. plot.new() signals to R that a new plot is to be produced. This will open a new. graphics window if there is none open, otherwise an existing window is readied to hold the new plot.
How about something like:
plot.new()
I suggest that someone needs to make empty plot in order to add some graphics on it later. So, using
plot(1, type="n", xlab="", ylab="", xlim=c(0, 10), ylim=c(0, 10))
you can specify the axes limits of your graphic.
The following does not plot anything in the plot and it will remain empty.
plot(NULL, xlim=c(0,1), ylim=c(0,1), ylab="y label", xlab="x lablel")
This is useful when you want to add lines or dots afterwards within a for loop or something similar. Just remember to change the xlim and ylim values based on the data you want to plot.
As a side note:
This can also be used for Boxplot, Violin plots and swarm plots. for those remember to add add = TRUE to their plotting function and also specify at = to specify on which number you want to plot them (default is x axis unless you have set horz = TRUE in these functions.
This is marginally simpler than your original solution:
plot(0,type='n',axes=FALSE,ann=FALSE)
Adam, following your comment above ("I wanted the empty plot to serve as filler in a multiplot (mfrow) plot."), what you actually want is the mfg option
par(mfg=c(row,column))
- which controls where you want to put the next plot. For instance, to put a plot in the middle of a 3x3 multiplot, do
par(mfrow=c(3,3))
par(mfg=c(2,2))
plot(rnorm(10))
You need a new plot window, and also a coordinate system, so you need plot.new() and plot.window(), then you can start to add graph elements:
plot.new( )
plot.window( xlim=c(-5,5), ylim=c(-5,5) )
points( rnorm(100), rnorm(100) )
axis( side=1 )
