I might be missing something super obvious here, but I'm trying to make a histogram and when I run the code it says "Error in hist(no_car) : object 'no_car' not found" even though I can run regressions and other functions just fine. I'm typing everything correctly but I'm not sure what I'm doing wrong.
hist(county_coded)
Error in hist(county_coded) : object 'county_coded' not found
I ran a regression with the same variable and had no trouble
Then redo your regression and do the hist immediately after the regression.
If you closed your R session after doing the regression and then start a new session
you have to recreate the variables you used (if you want to continue your analysis).
You can save and reload the contents of your workspace, but in general I think it is better to save the code that you use (as an R file) and rerun it when needed.
Just tried that, still no luck. Do i need to create the variables if they're in the dataset that I'm using?
i think i figured it out, i did this: > hist(transpo_times_Sheet1$county_coded) and it worked!
I think you did something like (using an example from here )
income.happiness.lm <- lm(happiness ~ income, data = income.data)
in that case your variable is a column of a data.frame and to plot it you could use
hist( income.data$happiness)
So in your case the name of the data.frame that you use followed by "$county_coded"
that worked thank you so much!!
That is good!
