I’m trying to accomplish something that shouldn’t be that difficult, yet it escapes my tries.
So I have an R Data Frame which looks something like this:
MeanTemperature(ºC) Longitude Latitude Height FinalConsiderations 5 91ºW 152ºS 548m Slightly Cooler 16 185ºE 53ºN 722m Unchanged 22 16ºW 2ºS 206m Significantly Warmer
The dataframe is a result of a filtered analyzed data. The end product is an Excel (xlsx) where the final column is the conclusion of the overall analysis. So, those steps are all taken care of, but these tables are rather large, so it would be nice to be able to color, for example, in RED where it says “Significantly Warmer”.
I’ve tried using the workbook from said dataframe
wb <- loadWorkbook(file) #where file is the location path
Here I want to collect those cells where it reads ‘Significantly Warmer’ in red, and afterwards export the workbook to xlsx.
fo1 <- Fill(foregroundColor="blue") # create fill object # 1 cs1 <- CellStyle(wb, fill=fo1) # create cell style # 1 sheets <- getSheets(wb) # get all sheets
But now I can’t find a way of making a function in the wb setting where at the $FinalConsiderations column == ‘Slightly Cooler’, the cells foreground is colored red, afterwards exporting to xlsx.
So I’ll write how I solved it, in case it helps anyone with a similar situation.
I downloaded the
library(openxlsx) #recall the library wb <- createWorkbook() # create a workbook addWorksheet(wb, "Sheet", gridLines = TRUE) #add a worksheet to the workbook writeData(wb, "Sheet", df) # write my analysis into the worksheet of the workbook, #where df is the name of my data frame
Afterwards, I create the styles, following the
createStyle function (see documentation).
In my case, I had to look for specific characters in my data
warm1Style <- createStyle(fontColour = "#000000", bgFill = "#FFFF00") # here search for the respective HEX color-code and assign a name to the style conditionalFormatting(wb, "Sheet", cols = 1:5, rows = 1:50, rule = "Significantly Warmer", style = warm1Style, type = "contains") # account the condition where "Significantly Warmer" is contained in a cell, # then apply the respective style to it (in this case, warm1Style)
Then that’s it, like so it can be done to any phrase or characters in the workbook.
Finally, save the workbook as an xlsx:
saveWorkbook(wb, file, overwrite = TRUE)
Thanks for the response
