[BlindRUG] Question about R Markdown

Hello,

I found some errors in your code. You forgot to enclose the main
title, x and y labels with quotations.

I hope the following lines of codes could help you.


dice <- sample(1:6, 50, replace = TRUE)
table(dice)
round(table(dice) / 50, digits = 3)

# Use BrailleR to get alternative text:
library(BrailleR)

VI(
    hist(dice,
        main = "dice role",
        xlab = "Number of dice", ylab = "Number of throws when rolling
the dice",
        col = "blue"
    )
    # Comment out the following line; otherwise, BrailleR cannot treat
this object:
    # box()
)

# Create tactile graph using tactileR package developed by JooYoung Seo.
# Install package:
if (!require(remotes)) {
    install.packages("remotes")
}

remotes::install_github("jooyoungseo/tactileR")

# Loading tactile package:
library(tactileR)

# Create tactile graphic by surrounding between two functions like
below. The arguments used in this example are all given by default:
brl_begin(file = "tactile.pdf", pt = 11, paper = "special", font = "BRL")
hist(dice,
    main = "dice role",
    xlab = "Number of dice", ylab = "Number of throws when rolling the dice",
    col = "blue"
)
box()
brl_end()
# The braille ready-to-print pdf version will be created in your
working directory. Print it out and run the swell touch paper through
swell form heating machine.
# Note: This function optimizes for both 1111 and 118.5 swell touch
papers. When printing a generated braille pdf, just remember two
things:
# 1. check “Fit” in the print dialog box (the shortcut key is ALT+F).
# 2. Check “Landscape” in the print dialog box as well.
# For boxplot, you do not need to check the “Landscape,” just leave it
as a “Portray.” However, please check the “Fit” all the time.
