Question

我有这样的数据

df<-structure(list(X = structure(3:1, .Label = c("CQLSKGQSYSVNVTFTSNIQSKSSKAVVHGILMGVP", 
"KLALQLHPDRNPDDPQAQEKFQDLGAAYEVLSDSEKRKQYD", "MVEAIVEFDYQAQHDDELTISVGEIITNIRKEDGGWW"
), class = "factor")), class = "data.frame", row.names = c(NA, 
-3L))

我试图突出显示每一行中的字母D，然后将其保存在xlsx中。我尝试使用此Excel Cell Coloring using xlsx

library(xlsx)
# To export the data
sheetname <- "mysheet"
write.xlsx(d, "mydata.xlsx", sheetName=sheetname)
file <- "mydata.xlsx"
# I want to color special letters in one cell
wb <- loadWorkbook(file)              # load workbook
fo1 <- Fill(foregroundColor="blue")   # create fill object # 1
cs1 <- CellStyle(wb, fill=fo1)        # create cell style # 1
sheets <- getSheets(wb)               # get all sheets
sheet <- sheets[[sheetname]]          # get specific sheet
rows <- getRows(sheet, rowIndex=2:(nrow(df)+1))     # get rows
# 1st row is headers
cells <- getCells(rows, colIndex = 2:cols)         # get cells
values <- lapply(cells, getCellValue) # extract the cell values

接下来，我们找到需要突出显示的字母

# find cells meeting conditional criteria D
highlightblue <- NULL
for (i in names(values)) {
  x <- as.character(values[i])
  if (x == D && !is.na(x)) {
    highlightblue <- c(highlightblue, i)
  }    
}

应用格式并保存工作簿。

lapply(names(cells[highlightblue]),
       function(ii) setCellStyle(cells[[ii]], cs1))
saveWorkbook(wb, file)

但是，我无法弄清楚如何为单元格中的字母着色。

我们如何突出显示特定字母并将其保存到xls
