read.xlsx()函数介绍
read.xlsx(
xlsxFile,
sheet,
startRow = 1,
colNames = TRUE,
rowNames = FALSE,
detectDates = FALSE,
skipEmptyRows = TRUE,
skipEmptyCols = TRUE,
rows = NULL,
cols = NULL,
check.names = FALSE,
sep.names = ".",
namedRegion = NULL,
na.strings = "NA",
fillMergedCells = FALSE
)
- xlsxFile:一个xlsx文件
- sheet:sheet的名字或者索引
- startRow:开始读取数据的行，文件前面的空行总是会被跳过并忽略startRow
- colNames:如果TRUE,数据的第一行就被作为列名使用
- rowNames:如果TRUE,数据的第一列会被作为行名使用
- detectDates:如果TRUE,将会尝试识别时间对象
- skipEmptyRows:如果TRUE, 空行将会跳过，否则数据行之后的空行用NA填充
- skipEmptyCols:如果TRUE，空列将会跳过
- rows:接受一个整数向量来指定需要读取的行号，如果是NULL则会读取全部的行
- cols:接受一个整数向量来指定需要读取的列号，如果是NULL则会读取全部的列
- check.names:如果TRUE,数据框中的变量名称将会被检查以保证其语法上是正确的
- sep.names:接受一个字符，用去替代空的列名，默认值为’.’
- na.strings:指定缺失值的字符串，空的单元格也会被认为是缺失值
- fillMergedCells：如果TRUE,合并单元格中的值会分配给每一个被合并的单元格内

writeData()和writeDataTable()函数介绍
writeData(
wb,
sheet,
x,
startCol = 1,
startRow = 1,
array = FALSE,
xy = NULL,
colNames = TRUE,
rowNames = FALSE,
headerStyle = openxlsx_getOp("headerStyle"),
borders = openxlsx_getOp("borders", "none"),
borderColour = openxlsx_getOp("borderColour", "black"),
borderStyle = openxlsx_getOp("borderStyle", "thin"),
withFilter = openxlsx_getOp("withFilter", FALSE),
keepNA = openxlsx_getOp("keepNA", FALSE),
na.string = openxlsx_getOp("na.string"),
name = NULL,
sep = ", ",
col.names,
row.names
)
writeDataTable(
wb,
sheet,
x,
startCol = 1,
startRow = 1,
xy = NULL,
colNames = TRUE,
rowNames = FALSE,
tableStyle = openxlsx_getOp("tableStyle", "TableStyleLight9"),
tableName = NULL,
headerStyle = openxlsx_getOp("headerStyle"),
withFilter = openxlsx_getOp("withFilter", TRUE),
keepNA = openxlsx_getOp("keepNA", FALSE),
na.string = openxlsx_getOp("na.string"),
sep = ", ",
stack = FALSE,
firstColumn = openxlsx_getOp("firstColumn", FALSE),
lastColumn = openxlsx_getOp("lastColumn", FALSE),
bandedRows = openxlsx_getOp("bandedRows", TRUE),
bandedCols = openxlsx_getOp("bandedCols", FALSE),
col.names,
row.names
)
- wb: A Workbook object containing a worksheet.
- sheet : The worksheet to write to. Can be the worksheet index or name.
- x: Object to be written. For classes supported look at the examples.
- startCol :A vector specifying the starting column to write to.
- startRow:A vector specifying the starting row to write to.
- array: A bool if the function written is of type array
- xy: An alternative to specifying startCol and startRow individually. A vector of the form c(startCol, startRow).
- colNames: If TRUE, column names of x are written.
- rowNames : If TRUE, data.frame row names of x are written.
- headerStyle: Custom style to apply to column names.
- borders: Either “none” (default), “surrounding”, “columns”, “rows” or respective abbreviations. If “surrounding”, a border is drawn around the data. If “rows”, a surrounding border is drawn with a border around each row. If “columns”, a surrounding border is drawn with a border between each column. If “all” all cell borders are drawn.
- borderColour :Colour of cell border. A valid colour (belonging to colours() or a hex colour code, eg see here).
- borderStyle: Border line style
- withFilter: If TRUE or NA, add filters to the column name row. NOTE can only have one filter per worksheet.
- keepNA : If TRUE, NA values are converted to #N/A (or na.string, if not NULL) in Excel, else NA cells will be empty.
- na.string: If not NULL, and if keepNA is TRUE, NA values are converted to this string in Excel.
- name :If not NULL, a named region is defined.
- sep: Only applies to list columns. The separator used to collapse list columns to a character vector e.g. sapply(x$list_column, paste, collapse = sep).
- row.names, col.names: Deprecated, please use rowNames, colNames instead
write.xlsx(x, file,startCol=1,startRow=1, asTable = FALSE, overwrite = TRUE, ...)
- x :一个data.frame或者list对象，满足可以被writeData()或writeDataTable()写出的要求
- file: 用于写出xlsx文件的路径
- startCol:开始写入数据的列
- startRow:开始写入数据的行
- asTable: 如果TRUE将调用writeDataTable()否则将调用writeData()写出数据
- overwrite：如果是TRUE则重写已经存在的文件，默认是TRUE
实例
mywb <- createWorkbook()
addWorksheet(mywb, "Cars")
addWorksheet(mywb, "test")
writeData(wb=mywb,
sheet='test',
x=df,
startCol = 2,
startRow = 2,
colNames = TRUE,
rowNames = TRUE,
headerStyle = openxlsx_getOp("headerStyle"),
borders = openxlsx_getOp("borders", "columns"),
borderColour = openxlsx_getOp("borderColour", "red"),
borderStyle = openxlsx_getOp("borderStyle", "thin"),
keepNA=TRUE,
na.string = '缺失值'
)
saveWorkbook(mywb, "test.xlsx", overwrite = TRUE)
