[BlindRUG] Question about R Markdown

Sun Mar 21 12:57:30 UTC 2021

Hi, I modified my R code and used the histogram function. I hope this
is correct now.

dice<-sample(1:6,50,replace=TRUE)
table(dice)
round(table(dice)/50,digits = 3)
hist(dice,main=dice role,
xlab=Number of dice,ylab=Number of throws when rolling the dice,
col=blue)
box()

 The question is how do I embed the code back into the .rmd. Is the
fig.cap in the file absolutely necessary?

What is the best way to plot histograms if you want to use brailler?

Kind Regards

Niels
