[BlindRUG] Reading output and easily understanding which number corresponds to what

Sun Oct 15 01:13:02 UTC 2023

Hello all,

For the purposes of anyone reading JooYoung's excellent suggestion, I'd note that the only reason his suggestion is useful is because he has assumed the user is operating in an R markdown (or Quarto) workflow.

(If I recall correctly this is true for Miso.)

I have to admit that my emphasis on helping improve the accessibility of R output has move heavily towards this workflow.

I know it places some extra burden on blind people if their classmates aren't using markdown. On the other hand, I'm also tiring of poor educational outcomes arising from students in the mainstream not getting taught how to use the modern tools and enjoying the corresponding advantages.

Courses not using a reproducible workflow are (IMO) frequently 20th century thinking with a newer interface. The students who will end up getting further on life as creators of information using data will be the ones who are the most efficient and effective.

All professionals need to allocate time for personal development; I believe that this is even more crucial for blind people who are already at risk of seeming less efficient or less effective as compared to their sighted colleagues.

There are exceptions. I am well aware of an increasing number of blind people who like me are efficient and effective in their chosen fields, not all of whom use the most modern tools. At some stage though, I hope these people are taking some time to evaluate how much longer their current practices are going to sustain them in a competitive world. I know I continue to evaluate my own practices, and do so frequently.

Jonathan

Hello Miso,

Yes, that's possible. Please find the following code snippet and I hope that this helps. I have included the R code inside the r codeblock.

``` r
# Install the following packages first if not available
library(tidyverse) # This is for data wrangling in general
library(tidymodels) # Useful package for modeling
library(gt) # making  publication-ready table

# Save your model
out.lm <- lm(dist ~ speed, data = cars)
# Use tidy function to make your model as a tidy grid form
tidy(out.lm) %>%
  # Use gt function to display the output in your browser as an html format
  gt()
```

All the best,

JooYoung

Hello,
I am having a difficulty asking this question succinctly so I am pasting *parts of my code* and output below. I imagine this is an easy question for expert R users.

> summary(out.lm)
Call:
lm(formula = mathpre ~ collgpaa, data = scs)
Residuals:
    Min      1Q  Median      3Q     Max
-6.0465 -1.9008 -0.0637  1.8426  6.6097
Coefficients:
            Estimate Std. Error t value Pr(>|t|)
(Intercept)   3.4122     0.7581   4.501 1.13e-05
***
collgpaa      1.0384     0.2655   3.912 0.000124
***
---
Signif. codes:  0 '***' 0.001 '**' 0.01 '*' 0.05
'.' 0.1 ' ' 1
Residual standard error: 2.646 on 208 degrees of
freedom
Multiple R-squared:  0.06852,   Adjusted R-squared:  0.06405
F-statistic:  15.3 on 1 and 208 DF,  p-value: 0.0001241

In the part of this output that shows coefficients, I can tell that estimate std error is 0.7581 and T-value is 4.501, by memorizing the placements of std error, t-value and Pr(>|t|). And knowing what kinds of number to expect I guess could work in most cases I may run into.
I believe my sighted colleagues are able to easily place which number belongs to what by looking at how they are placed (4.501 directly underneath t value for example).
Perhaps as I practice more, I will become more efficient over time but I am curious, is there a way I can make the process of reading the output and placing which number belongs to where more efficient for? E.g., having this be displayed in a list format or table format that I can navigate cell by cell vertically?

Thank you for your consideration and any suggestion you may be able to offer.
