change unit... plot R

[Jeremy98-alt]

hi guys,
I've a problem with the axes because, I want to plot like x axis 0 to 3 and like y axis 0 to frequency x, but without 3.5, 2.5 etc.... How can i fix it?

kind regards!

Here is an example of using the default axis tick marks and then using customized ones.

DF <- data.frame(ColA = 1:3, ColB = 1:3)
plot(ColB ~ ColA, data = DF) #original plot

#modified axes
plot(ColB ~ ColA, data = DF, xaxt = 'n', yaxt = 'n') 
axis(side = 1, at=1:3)
axis(side = 2, at=1:3)

@FJCC

plot(ColB ~ ColA, data = DF, xaxt = 'n', yaxt = 'n') 
axis(side = 1, at=1:3)
axis(side = 2, at=1:3)

thank you @FJCC or the answer, but see this image.... this is the result how can I fix it? this is really strange!

I found a way to change the unit but I want to know How to remove the gap on x and y axes from the point 0,0 on x and y...

kind regards

I am not sure exactly what you want to change about the plot. Below is an example of changing how the two axes cross.

It would be easier to help you if you would make a reproducible example (reprex) rather than post pictures of your code. Here is a tutorial about that.

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…

DF <- data.frame(X=0:3,Y=4:1)

plot(DF, ylim = c(0,4))

#bty = "n" suppresses the printing of the box around the plot. 
plot(DF, xaxt = "n", yaxt = "n", bty = "n", ylim = c(0,4))
axis(side = 1, pos = 0)
axis(side = 2, pos = 0)
