It's possible add greek letter with renderTable?

[Ivan Bezerra Allaman]

Good afternoon gentlemen!

I would like to include Greek letters on my table. Here is a part of the script to further elucidate my doubt.

.
.
.
 sliderValues <- reactive({

              #
             data.frame(
                         Estatísticas = c('mu',   #here!
                                           "sigma",   #here!
                                           "dqm",
                                           "s2"),        #s^2???
                         Valores = as.character(c(input$mu,
                                                  input$sigma,
                                                  dqma(),
                                                  s2())),
                         stringsAsFactors=FALSE)
            })                                   

 output$view <- renderTable({
              sliderValues()
            }) 
.
.
.

Thanks!!

Hi Joe!

I've tried "mu", "$mu$", "$\\mu$" and appears "mu", "$mu$" and "$\mu$" respectively and not the Greek letter as I would like. I looked in several places how to insert Greek letters in data.frame, and found nothing. I know that with graphics you can use the expression function, more data.frame not know and have not found how to do this. Researched here in the group too, but it seems that nobody has gone through something similar. From what I've researched, it is the function xtable behind the constructions of the tables, so I thought that a simple "$ \ \ mu $" was enough. Most did not work. Any suggestions?

Thank you.

Have you tried using '𝚺' and  'μ'? (Hopefully those will appear correctly for you)

Hi Winston!

How???? I do not see how to insert symbols, greek letters except for commands like $ \ mu $, $ \ sigma $, etc.. The way you posted, I see the possibility using the toolbar windows in which you ask to enter a particular symbol. Any suggestions?

[Winston Chang]

I just used the character browser (under Edit -> Special Characters) on my Mac. Perhaps you can copy and paste these characters into your code?

Hummmmmmmmmmmmmmmmmmmmmmm! It's like I say: Why to complicate?

Thanks!

Did this work for you?  I ran across the same problem, importing and displaying a CSV with text like "Units,µg/kg (ppb)".

I get an "Input string 2 is invalid at this locale"  error message when i try to render a table from that data.

Hi Jason, are you on Windows?

I'm on Mac OSX 10.8.3

As a workaround, I applied gsub to the data frame to swap the mu for a lowercase 'u', but I'd much rather have the original text.

Is the CSV file encoded with UTF-8? If so, I would expect that to work. If it's UTF-8 and still not working, can you send me the contents of your sessionInfo()? Thanks.
