r markdown, knitr and latex symbols












1














After several hours of searching for an answer to no avail, I thought I'd seek advice here.



I'm trying to produce some very simple html tables using knitr in r markdown, but I can't get the latex symbols to display correctly in the column names.



Example code, with several different symbols:



kable(data.frame("$^3$" = "a",

                  "$\epsilon^2$" = "b",

                  "$%$" = "c"),

                  escape = F)


Here's the output



As you can see the column names are not formatted X..3. X..epsilon.2. X...



Any help would be much appreciated

You can use those column names in a data frame, but you need to tell the data.frame function not to mangle them using check.names = FALSE.
However, this isn't enough to fix your example, because $%$ is not legal LaTeX.
You need to escape the percent sign or it will be taken to be a comment character.
So this works:



my_data <- data.frame("$^3$" = "a",

                      "$\epsilon^2$" = "b",

                      "$\%$" = "c",

                      check.names = FALSE)

kable(my_data)

You can set the col.names in your kable-call. It does not work in your data.frame-call, because that does not allow column names which don't start with a dot or letter.
You can see this here: 



my_data <- data.frame("$^3$" = "a",

                      "$\epsilon^2$" = "b",

                      "$%$" = "c")

my_data

  X..3. X..epsilon.2. X...

1     a             b    c


The solution is: 



kable(my_data, escape = F, 

      col.names = c("$^3$", "$\epsilon^2$", "$%$"))


enter image description here



You might want to use varepsilon instead of epsilon as this gives a prettier epsilon (in my opinion). 



kable(my_data, escape = F, 

      col.names = c("$^3$", "$\varepsilon^2$", "$%$"))

my_data

  X..3. X..epsilon.2. X...

1     a             b    c


The solution is: 



kable(my_data, escape = F, 

      col.names = c("$^3$", "$\epsilon^2$", "$%$"))


enter image description here



You might want to use varepsilon instead of epsilon as this gives a prettier epsilon (in my opinion). 



kable(my_data, escape = F, 

      col.names = c("$^3$", "$\varepsilon^2$", "$%$"))
