# Knit a R Markdown to a HTML

Everything work fine in the RMarkdown file. However when I want to generate an HTML doc, I have an error message. I cannot export my work to HTML. I work with MAC OS Ventura 13.1.

|............ | 22% (setup)

processing file: Cronbach_attitudes.Rmd

Quitting from lines 29-31 (Cronbach_attitudes.Rmd)
Calls: ... withVisible -> eval_with_user_handlers -> eval -> eval
Execution halted

Without more details it is hard to say but it looks like Quarto is executing an R routine and it cannot find a variable Invscore230223.

Does that routine run in a regular R environment.?

I work in R studio Version 2022.12.0+353 (2022.12.0+353).
If I delete the chunks with the object name (i.e. Inyscore230223). I have an HTML output with the following code :

However, I have lost all the output of results (i.e. data.frame results). I am sure I miss something when I generate the HTML document to keep the results inside .

Many thanks again for your help.

I think we need to see the actual Quarto file and a sample of your data. You can cut out most of the verbiage but we need the YAMAL and all the coding.

Have a look at this FAQ for some suggestions on setting up a question on the forum. Oh, and I forgot; wercome to the forum.

A handy way to supply some sample data is the dput() function. In the case of a large dataset something like dput(head(mydata, 100)) should supply the data we need. Just do dput(mydata) where mydata is your data. Copy the output and paste it here.

I have reproduced the same error with other data .frame of a smaller size

We really need to see what you are doing. For example here is a very simple .qmd file. I don't have a .rmd one handy .

However if r x[5] roses and 1 violet are enough, we should be fine.

## I am sorry to be so incompetent in R but I am a beginner. Here is the YAML code of what I have done in RMarkdown --- title: "Alien_data_test" author: "AnneClaude Griesser" date: "2023-02-25" output: html_document

knitr::opts_chunk\$set(echo = TRUE)


Create a subset of data

Alienselect<- c("sp12.1_catcar","sp12.2_poscar", "sp13.1_blank", "sp13.2_high", "sp13.3_hide", "sp14.1_door", "sp14.2_comf", "sp14.3_posit")
ALienselect8 <- aliendata_20230225[Alienselect]

alpha(ALienselect8)

dput(head(aliendata_20230225))

Some things are user-friendly. R is beginner-hostile.

The problem is here

ALienselect8 <- aliendata_20230225[Alienselect]


ALienselect8 <- aliendata_20230225[  , Alienselect]


In the format dat[ , xx] you are telling R that you want to select all rows of the columns in xx. dat[ 1, xx ] says you want the first row.

For dput() you want to copy the output and paste it here. See example below.

dput(dat2)
structure(list(A = c(0L, 0L, 0L, 0L, 1L), B = c(0L, 1L, 1L, 93L,
42L), C = c(965L, 3L, 313L, 15L, 2L), D = c(0L, 0L, 0L, 21L,
34L), E = c(0L, 0L, 0L, 46L, 109L)), row.names = c(NA, 5L), class = "data.frame")


Many thanks for having found out my error and for me giving an example. However, I don't understand what this has to do with the problem when I generate an R markdown that aborts indicating that it doesn't know an object data.frame

• what this has to do with the problem *
Well the .rmd file will not compile with that error.

Without a (semi) working example of your Rmarkdown file and some sample data we really cannot do much.

If you take my .qmd example above and drop it into an empty .qmd file you should be able to compile it. We need a copy your equivalent file.

Thank you very much for your help. I am conscious that I am lost and what is very obvious and simple for you seems insurmontable to me. I am convinced that a copy of my file would be of great help. Unfortunately, I did not succeed in reproducing your example. I am sorry and I propose that we leave at that. Many thanks again for your help and support.

Okay, sorry not to be of more help.

Usually this error comes from when a R variable is not available to R Markdown process. Where is Invscore230223` loaded or defined in your Rmd file ?

I can't see it your example in the posts after ...

Same question: Where is the data loaded or created ? Is this correctly done inside your Rmd file ?

When you click Knit / Render on a document in R Studio IDE, it will open a new clean R session and render the document. This means that all your data and any variable needs to be defined inside the Rmd file. You can't rely on variable already available in your R session that would have been loaded otherwise - this could work when working interactively but it won't if you render in a clean session your Rmd file.

Best practice is to have a Rmd file that can be run on its own - this means all the variables used need to be defined (with value / data created or loaded in the Rmd file itself)

Hope it helps
