Hello,
I am trying to write a function which automatically loads a CSS into a shiny app as the shinytheme function from the shinythemes package, which has the following code:
shinythemes::shinytheme
function (theme = NULL) *
{
if (is.null(theme) || !theme %in% allThemes()) {*
stop(theme, " is not an available theme. Valid themes are: ", *
paste(allThemes(), collapse = ", "), ".")*
}
paste0("shinythemes/css/", theme, ".min.css")*
}
I tried to modify it and write my own function, which has solely one theme file as an inout, and is therefore a function without an argument (so I do not need the if (is.null(theme) || !theme %in% allThemes()) {... part), I saved a CSS named mytheme.min.css in the given folder
example:
mytheme <- function ()
{
paste0("C:\\Users\\Me\\Documents\\", "mytheme", ".min.css")*
}
I tried it with a shinyApp, but unfortunately this does not work and it loads with the default theme
ui <- fluidPage(
theme = mytheme(),
titlePanel("Hello Shiny!"),
sidebarLayout(
sidebarPanel(
sliderInput(inputId = "bins",
label = "Number of bins:",
min = 1,
max = 50,
value = 30)
),
mainPanel(
plotOutput(outputId = "distPlot")
)
)
)
server <- function(input, output) {
output$distPlot <- renderPlot({
x <- faithful$waiting
bins <- seq(min(x), max(x), length.out = input$bins + 1)
hist(x, breaks = bins, col = "#75AADB", border = "white",
xlab = "Waiting time to next eruption (in mins)",
main = "Histogram of waiting times")
})
}
shinyApp(ui, server)
If someone could tell what I have to change in order to make this work, I would be grateful.
