I am new to R and am running into trouble with the function plot.
When I enter in the simple code:
x<-1:4
y<-5:8
plot(x,y)
I get a scatter plot with 4 points as expected.
However, with my own data, A and B are both vectors of length ~85, each
entry a decimal in [0,1].
Using the same plot(A,B) with this data, the plot function no longer gives
me a simple plot with 85 points. Instead there are many points, and what
looks to be several box&whisker plots also included on the plot.
This is a link to the actual output.

Why is the plot function doing this? How can I get it to simply give me a
scatterplot? (From there I want to do a lsline, etc..)
Any help is greatly appreciated...
Most likely your A vector is not numeric: it's being read as strings
like "0.4688", etc. Take a look at str(A) and str(B) to see their
structure. (I can't tell from the plot, but I'd guess it's being read
as a factor, because some of the values are not recognized as numeric.)
