dataframe - R-Shiny renders wrong results in a DataTable -


i programmed app in shiny, calculated results totally wrong :(.

i have got data.frame:

          label v1      v2 1 begeisterung    6      3 2        basis    2      4 3     leistung    5      4 4  indifferent    4      6 5      reverse    0      0 6  fragwuerdig    1      1

i have calculate score "v1 , "v2". done following code:

cs_minus1 <- (ergebnis[2,2] + ergebnis[3,2]) / ((-1)*(ergebnis[1,2] + ergebnis[2,2] + ergebnis[3,2] + ergebnis[4,2])) cs_minus2 <- (ergebnis[2,3] + ergebnis[3,3]) / ((-1)*(ergebnis[1,3] + ergebnis[2,3] + ergebnis[3,3] + ergebnis[4,3]))

results are: -0.4117647 -0.4705882

when calculate in normal r, absolutely works fine. in shiny receive -0.4117647 0

i have absolutely no clue, why results in shiny differ.

edit: shiny code

output$tb <- renderui({     if(is.null(datensatz())){       return ()     } else       tabsetpanel(tabpanel("about file", tableoutput("filedf")),tabpanel("cs koeffizienten", dt::datatableoutput("table")),                    tabpanel("faktoren", dt::datatableoutput("table2")), tabpanel("plot", highchartoutput("table3")), tabpanel("interpretation", htmloutput("interpret")))   }) })

if use code, wrong values.

      output$tb <- renderui({       tabsetpanel(tabpanel("about file", tableoutput("filedf")),tabpanel("cs koeffizienten", dt::datatableoutput("table")),                    tabpanel("faktoren", dt::datatableoutput("table2")), tabpanel("plot", highchartoutput("table3")), tabpanel("interpretation", htmloutput("interpret")))   }) })

if render ui without condition works fine , can see correct val. don´t understand why, me makes no sence. seems bug me.
