readxl

问题 I have a group of Excel files with multiple sheets which don’t follow a standard naming convention. I want to create a single data frame from specific sheets containing the keyword 'frame' . library(tidyverse) library(openxlsx) # Sample Excel File 1 df1 <- data.frame(replicate(10,sample(0:1,10,rep=TRUE))) data_frame2 <- data.frame(replicate(10,sample(0:1,10,rep=TRUE))) list_of_datasets1 <- list("df" = df1, "date_frame" = data_frame2) write.xlsx(list_of_datasets1, file = "writeXLSX1.xlsx") #

问题 I have multiple .xls (~100MB) files from which I would like to load multiple sheets (from each) into R as a dataframe. I have tried various functions, such as xlsx::xlsx2 and XLConnect::readWorksheetFromFile , both of which always run for a very long time (>15 mins) and never finish and I have to force-quit RStudio to keep working. I also tried gdata::read.xls , which does finish, but it takes more than 3 minutes per one sheet and it cannot extract multiple sheets at once (which would be very

问题 I want to import multiple sheets, selected by a common string in the sheet name, from a single .xlsx file and concatenate them into single data frame. For example, if I have an excel file ('data.xlsx') with worksheets named samples1, samples2, samples3, controls1, controls2, controls3. I want to make a list of the worksheet names, such as: sheet_list <- lapply(excel_sheets('data.xlsx'), read_excel, path = 'data.xlsx') Then, I want to import all sheets that contain 'samples' in the name and

问题 Hi guys I'm having difficulty loading .xlsx into RStudio - I'm not sure why RStudio can't see the file. Am I specifying the path for read_excel() wrong? Any ideas? Pretty new at R. Thanks!
