formatting - Conditionally coloring a cell in htmlTable for R -

-

i'm using excellent htmltable package printing results in rmarkdown. 1 of tables shows values between 0 1. have generated vector of 100 colors interpolated between white (#ffffff) , red (#ff5555) i'd match each cell's background depending on it's value.

the logical part clear me (multiply cell's value 100, round , extract color corresponding index of color vector).

what i'm not sure is, having matched color each cell, how make htmltable paint it?

thanks!

i think can using rgb colors like:

paste0("background-color:rgb(255, ",value*255," , ",value*255 ," )"

where value cell value 0 1

example( 0 red,1 white)

 df = as.data.frame(matrix(round(runif(15, 0, 1), 1),ncol = 3 ))  htmltable::htmltable(df,css.cell=apply(df,c(1,2),function(i)paste0("background-color:rgb(255, ",round(i*255,0)," , ",round(i*255,0) ," )")))

i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response
