HI there I am learning R and using the MASS package., I have a histogram of Cars93 but none of the code to change the plot seem to work eg - xlab="Price(*1000)" or - xlim=c(0,70)
The plot just stays as is . I have tried deleting the plot and pressing the refresh button but no joy.
If this is not the place for these type of basic questions plese redirect me
thank You
Hi, welcome!
We don't really have enough info to help you out. Could you ask this with a minimal REPRoducible EXample (reprex)? A reprex makes it much easier for others to understand your issue and figure out how to help.
If you've never heard of a reprex before, you might want to start by reading this FAQ:
HI There
I have typed the code to change the heading of the graph as per the Reprex
xlim=c(0,70)
main="Prices of 93 Models of 1993 Cars"
<sup>Created on 2022-03-06 by the [reprex package](https://reprex.tidyverse.org) (v2.0.1)</sup>
But the heading on the graph dies not change. I am using the cars dataframe from the MASS package
The forum does not let me upload a picture of the plot because I am a new member. Sorry about that.
Basically changes I am trying to make to the plot do not reflect on the plot as if the code is not runningI think you are confusing base plotting with ggplot2 but you dont provide code that would produce any plot, so its that much harder to judge it.
