R Error: Object X not Found (2 Examples)
This tutorial explains how to reproduce and fix the error message “object X not found” in R.
The article contains the following topics:
Let’s start right away…
Example 1: Replicating the Error: object ‘x’ not found
Example 1 shows how to reproduce the error message “object X not found” in R.
Let’s assume that we want to return a data object called x to the RStudio console:
x # Trying to print data object to console # Error: object 'x' not found
As you can see based on the previous output of the RStudio console, the previous R code leads to the error message “”object ‘x’ not found”.
The reason for this is that the data object x does not exist.
Let’s fix this error…
Example 2: Fixing the Error: object ‘x’ not found
The following R programming code explains how to solve problems with the error “object X not found”.
For this, we have to define the object we want to use first:
x <- 1:10 # Assigning values to data object
Now, we can print this data object to the RStudio console:
x # Printing data object to console #  1 2 3 4 5 6 7 8 9 10

helo i’m calculating kideraFactor in R so i install peptide package but still i’m facing this Error: object ‘kideraFactors’ not found
Could you please share the code you have used so far?
I have pasted my code below along with the error message i face when I run a Rscript check in the terminal. This code seemes to work fine in Rstudio and the plot comes up but in the terminal it doesnt seem to recognise my dataset “score”, would you be able to help me understand where im going wrong ?
Thank you in advance,

ggplot(score, aes(Goals, MotM)) + geom_point(shape = 21, size = 1, colour = “red”)
Error in ggplot(score, aes(Goals, MotM)) : object ‘score’ not found
Thanks for the comprehensive description of your problem.
It looks like you are not creating a data object when reading the data set from your CSV file.
Does it work when you replace the second line of your code with the following syntax?
useless post haha
we are sorry that the post seems useless for you. But may it will help other people out there (tbh I’m pretty sure it already did).
for me, r brings the error, object X not found for the first variable that i wish to select.
here is the code:
sympts <- select(Symptom_ID, Total_Berries, `BerriesSymptom`, No.LesionsBerry, AverageCoverageBerry)
the out put:
Error in select(Symptom_ID, Total_RBD_Berries, `Berries Wiz d Symptom`, :
object 'Symptom_ID' not found
hoping for your reply
I think you are missing specifying your data. You should either do like:
