    You can't convert a plot object to a ggplot object. But you can use `ggplot` instead of `plot` in your code. What have you tried so far? Can you give us a [mcve]? –  Apr 01 '18 at 19:54

  • @kKenny Can you expand on this? What is your intended output vs actual? – NonCreature0714 Apr 01 '18 at 22:23

Using package ggplotify: https://cran.r-project.org/web/packages/ggplotify/vignettes/ggplotify.html

library(ggplotify)
res<-read.table(text="
s
\"2014-02-14 51.8460\"                                                         
\"2014-02-14 44.5080\" ", header=T)  
p <- as.ggplot(function() plot(res$s, type="n", main="title")  )
p

You cannot "convert" a graphic from base R to ggplot2. You have to replot the data. ggplot2 provides the function qplot()that has a syntax similar to plot().

If you have a two column dataframe: df$x and df$y, 

qplot(df$s,df$y, geom='line')

should do what you want.
