R help - Nov 2014 - ggplot question error: Error in s(x, bs = "cs") : object 'x' not found

Dear R-ers,

apologies for not providing the full code. I just need a point in the
right direction.
I have a data frame ('temp') with 1,200 rows and 2 variables.
I am using ggplot2 to create a scatter plot:

This is my code and it works fine, it creates a scatter plot:

library(ggplot2)
sp10<-ggplot(temp,aes(x=p.used_L1,y=l.to.r.ratio_L1))
sp10 + geom_point()

However, when I change the last line to:
sp10 + geom_point() + stat_smooth(se=FALSE)

Then I am getting these messages (and no fitted line on the graph):

geom_smooth: method="auto" and size of largest group is >=1000, so
using gam with formula: y ~ s(x, bs = "cs"). Use 'method = x'
to
change the smoothing method.
Error in s(x, bs = "cs") : object 'x' not found

I don't understand what x in in s(x, bs = "cs") is or should be.
I lookeed up ?geom_smooth and tried this:

sp10 + geom_point() + stat_smooth(se=FALSE,formula = l.to.r.ratio_L1 ~
p.used_L1)

Still, the same error message.

Thanks a lot for your advice!

Never mind, I found the problem.
In my profile s was assigned to summary.
This is why it did not work.

Hi Dimitri,

I am not sure I completely understand the issue but here is what I think you
want (using my variable names :) )

library(ggplot2)
dat1  <- data.frame(aa = sample(1:20, 100, replace = TRUE), bb = 1:100 )

p  <-  ggplot(dat1, aes(aa, bb)) + geom_point()
                  
p  <-  p + geom_smooth(se = FALSE) 
p
