summarytools | R Package to Quickly and Neatly Summarize Data

I have data similar to the NHANES data I call below. What I would like to do is loop over a list of several variables to create crosstabs. I would like to stick with the summarytools::ctable package because I want to call the chisq argument. However, happy to use another approach, so long as the chisquare is an option and I can still remove NAs.

Here is what works so far. I am able to use the function below to generate simple frequencies. However, I would like the name of the variable to print before the frequency table. The function first prints all of the variable names THEN goes on to generate the frequencies so that is issue # 1 that I am struggling with:

I am using freq from library(summarytools) to create some frequencies.

Example:

Apologies if this has been asked elsewhere / if I am using the wrong terms, I have been trying to search for the correct way to do this but with no success so far.

I have an experimental design with 3 experimental conditions using repeated measures outcomes (each participant completes 4 trials). The data I have currently is in long format (each participant ID is repeated 4 times). I am trying to calculate summary statistics for the demographic variables (age, gender, condition etc.) but I cannot figure out how to, for lack of a better word, collapse/merge the rows for each participant together to get the frequency data and/or summary stats.

Below I have a simulated dataset

I have data as follows and I want to get rid of the variable type mentioned in the output(red).

I'm a big fan of R's simple functions like table() for quickly viewing bivariate tables but when I want frequencies & percentages in the same output, I use ctable() from the summarytools package.

Sometimes I have long variable names, which is no problem for table(); I just do a quick rename in the table() function. However, I haven't figured out how to do the same sort of variable label renaming for the ctable() output. I found a few posts on SO about ctable() and labeling, but these pertained to other, more complex work such as involving kable() and Rmarkdown. I'm looking to keep everything tucked within the raw console output, preferable all within ctable() or perhaps nested inside another function like print().

Here are code examples of what I'd like to do and where I'm stuck so far.

I have a code as folows and my objective is to create an interactive data visialissation shinyapp but I can not print out the summarytool table properly which can be found in . Any help will be appriciated and many thanks in advance.

I am using R and I would like to export this summary as a PNG file. Can anyone help me please? Thank you!

Why does save_kable command of the kableExtra package results in bad resolution PDF? I have observed that when a PDF is rendered with magick(which is standard in kableExtra) the quality is pretty bad (see screenshot below). When magick is not installed, it works, but with another renderer (Qt5.5.1 in my case; Macbook Pro 2018, OSX 10.14.6; imagemagick@6 is installed vie brew). However, uninstalling R's magick, rebooting etc. works but is not convenient (especially if you need magick also for other R packages like summarytools) and therefore does not turn out to be a permanent solution. I might handle something not in the way it was intended and I am happy to get some help on this.

The explicit headers I add to a Rmd file (e.g. ## Section 1) are recognised fine using yaml like this:
