[BlindRUG] Taking a Statistics Course for the First Time

Fri Aug 26 10:04:16 UTC 2022

Hello Mitchell,

R users do not edit the data file.

We programmatically update it. This means we can specifically replace the incorrect entries for a variable by naming that variable and not need to know which column that variable is stored in.

If you are going to have to clean data, then I would recommend using the tools in the textbook "R for Data Science" which is online at 
https://r4ds.had.co.nz/
That book has plenty of other useful content.

If you use ggplot() to create graphs, then also be sure to download the BrailleR package which will give you some feedback on the graphs you have created. The package won't give you data insights, but it will tell you if the graphs you are giving to your sighted audience has the right content in it.

Finally, Liz has offered one way of working with R as a blind person. I consider my way of working to be about as interactive, but it is different to the Liz workflow. It is crucial that you work out what way works best for your personal and educational circumstances. 

When you subscribed to this list, you should have received some links to resources. Included among them is guidance on using R markdown. This is how I work, and it is how a massive quantity of online resources are made, including R4DS.

I am about ready to provide list participants with my views on the latest way of working that is being developed. Please watch this space.
We are seeing new developments in the wider R ecoverse that offer us more and more all the time.

Jonathan

Hello Liz, 

That's very helpful. I'll definitely try that out. Hopefully I'm understanding this correctly, but if anything else doesn't work, I can just use a "view" compand to read out the data and then "clean" the file for incomplete rows just from the command line, although the downside of reading the specific data from the command line (at least in my inexperienced opinion) would be that I would need to be completely sure that I remember what column referred to which specific variable. 
Best Regards,
Mitchell Bridwell

As noted earlier in the list (because I did my best to figure out if my question was answered), R Studio isn't the most accessible. I'm going to assume that this is also referring to R Studio Server Pro, although from my experience I have been able to use the shortcut (I think like Alt + shift + 2) to get to the console output. My main issue currently is reading imported data efficiently. When I attempted to use JAWS or NVDA with Chrome, a table with sort by headers showed up, but there didn't appear to be any data in the actual table, and the table with that data didn't  exist. I appologize if I missed anything that would have answered my questions.
