Hello I am trying to create a multiple regression but know nothing about using ggplot2 and don't even know if I can use it for my data because they have different data ranges, could someone please help me with the code to try or recommend another package to use if i can't use ggplot2. I am trying to plot species against area, distance to mainland and distance to nearest island and I am using the abbreviations s,a,dm and dn in my data. I don't think these have an interaction, someone please help me write the code!
What have you tried? Maybe you should post an example of your data and what you have done.

There's a great quick-look ggplot for x,y data that will give a quick look at y ~ x with an lm smoother. Using the famous mtcars dataset
suppressPackageStartupMessages(library(dplyr))
suppressPackageStartupMessages(library(ggplot2))
mtcars %>% select(mpg,wt) -> dat
p <- ggplot(dat, aes(wt,mpg))
p + geom_point() + geom_smooth(method="lm")
Created on 2020-03-02 by the reprex package (v0.3.0)
You can also create a line showing the intercept and slope from the lm model and various diagnostic plots.
