I am data science student and I am running into an issue while doing my hw and even my professor can’t figure it out.
When I use this code: associate(Size_of_Party~Smoker,data = EX2.TIPS, seed=9750), I get the following result.
As you can see from above, the p value of ANOVA is between 0.017 and 0.049 which means the test is conclusive.
However, when I knit the document, I get different results for the p value range for the anova test.
The p value in my knitted document is showing the p value to be between 0.028 and 0.066 for the ANOVA test which makes sense why it is inconclusive.
Does anyone know why this is happening?
I tried to download the latest R studio version, tried to re-run everything and the same thing keeps happening.
just curious: if you add set.seed(123) in the same code chunk and knit again, will that solve the problem?
Knitted documents sometimes cache their results to save time when re-knitting, and this can sometimes lead to issues where data isn’t updated when it should. Try disabling cache by adding
r opts_chunk$set(cache=TRUE)in the first chunk, and/or try restarting your R environment.The first image doesn’t show any pvalue. More generally, you should post complete code so we can evaluate it ourselves; we don’t have “associate” or “EX2.TIPS”.
