I have created a folder that has my dataset and set it as my working directory in Rstudio.
The dataset is an SPSS file which I named "Stats in R", I downloaded the packages foreign and Hmisc and tried to run to the following command to get the dataset:
data = read.csv("Stats in R.csv", header = TRUE)
…but the console showed the following message:
Error in file.choose() : file choice cancelled.
The problem is, my dataset is in the working directory but whenever I try to open it, R shows me an empty folder. I run the dir() command and instead of getting the directory content in the console, I get the following message:
character(0).
I really don't know what's the problem, the SPSS dataset is saved as a SAV file. I tried other extensions as well like CSV but nothing worked. Any suggestions, please? I really need to sort out that issue soon. Thank you!
It seems like you have some issue with your working directory - it's either not where you think it is, or you don't have full permissions and something is blocking the R Studio interface from accessing it.
Since you want to get this resolved quickly, the approach I would try is importing the file using the entire file path instead of the working directory, and then you can troubleshoot your WD when you have time.
This should work:
df <- read.csv("C://Users//Mina//Folder//Subfolder//Stats in R.csv", header = TRUE)

Whenever I knit to a PDF in RStudio, the error "The system cannot find the file specified."
Here is the code that I'm using:
##importing data
library(readr)
Quiz1data_2 <- read_csv("C:/Users/erinp/Downloads/Quiz1data-2.csv")
I have restarted RStudio multiple times and I have copied and pasted the exact link that my file is saved to and it's still not working.
What am I not seeing or what am I not thinking?
Some suggestions/questions:
Without knitting, when you run the line reading in the csv, does it work?
Also, are you sure that the error is referring to the data csv? Could it be referring to the (I'm assuming) markdown file you are writing your code in? Have you moved that file since you started working in it?
Are you able to knit other documents to pdf? You need MiKTeX on a windows machine. Does knitting to html work?
I've found R to be a little tricky reading in files. I usually use the base function like this:go to the environment tab>import dataset>from text(base)> (select the file you want, hit open)>(select settings so that the dataframe preview looks right>import. Code that does this will run in the console, and I copy it into my markdown file so that every time it knits, it replicates that successful process.
I figured it out. It's because I forgot to assign a value to an object so it wouldn't knit into a PDF. I made a comment earlier, but it's small so I thought I would add this to the answer section.
I am using R with readxl package. I try to import an Excel file with the following command:
library(readxl)
city_codes <- read_excel("./data/file.xlsx", sheet = "city_codes")
It says it is a zip file and cannot be opened:
Error in sheets_fun(path) :
Evaluation error: zip file './data/file.xlsx' cannot be opened.
Any ideas?
I had this error, but for me, it was just that I had the sheet open in Excel while trying to read it into R. I guess the package wrongly perceives it as a zip file when it's trying to read it while Excel has partial ownership of it (and this blocks the read).
The error message is readxl's funny way of saying "file not found". That exact line of code gives me the exact same error, and the file doesn't even exist for me.
Note: I'm on version 1.0.0 of readxl
For me the "Evaluation error: zip file" error message also appeared when the excel spreadsheet was still opened in MSExcel.
You can specify a path to a file, only if it is nested on the working directory.
For example: If your working directory is MyWD and there is a folder in it, named MyData and another folder within MyData named MyNestedData, and finally myExcelFile.xlsx
read_excel("MyData/MyNestedData/myExcelFile.xlsx",sheet = "Sheet2") #will work
read_excel("MyWD/MyData/MyNestedData/myExcelFile.xlsx",sheet = "Sheet2") #will not work
If your excel worksheet is password protected, read_excel won't be able to access it and will give you this error.
If it needs protection, I would suggest p/w protecting the folder it's in, and then unprotecting the worksheet.
You may also get this error if you are using the wrong read function.
For example, read_xlsx("file.xls" ...) will throw the error.
This can happen if you forget to do the following before you use the read_excel function
setwd("C:\\map\\map_in_map\\map_in_map_in_map_where_the_file_is")
Try to change file restrictions if you are working on company's computer. This worked for me to solve this issue.
You may try to specify the full path instead of ./path/to/file
Try to make a new file. click "save as" and make a new name. Run again your code. it worked well to me :)
Although the solution was already given, but for the sake of documentation I will leave my situation here:
I ran into the same problem and couldn't figure out why. It seems that my excel file had closed with an error or something similar. I had to open the excel file, and save it again. When I ran R, everything worked smoothly.
The issue was that there was hidden files inside my working directory. I copied them to outside and exclude all directories. Now it works when I run the code.
In my case the xlsx was created using Excel 2007, which caused this issue. Xlsx files from newer Excel versions work.
In my case the file was not visible in the directory although I had deleted it. I had to search for the file using a software called "Everyting" and I deleted it. After that it worked.
For me, I was downloading a file from Google Drive into a tempfile with extension .xlsx... Realised the file in Google Drive was .xls so I changed it to that and it worked. Kinda rare situation though.
I got the same error message.
In my case the line that worked properly specified the sheet by a string (copied from excel). Suddenly, it did not work anymore (with the mentioned error message). I tried several things explained here. Ended up specifying the sheet by its number in the excel file - worked!
read_xlsx("table.xlsx", sheet="name_of_sheet") # suddently corrupt
read_xlsx("table.xlsx", sheet=4) # works
Why? No update of the package or something. I dislike to have to use a less specific line.
UPDATE: Restarting the R session made the initial line work again (although, I HAD checked the wd before...)
Been using R for around two years now and this is the first time i've encountered this issue. I have a data.frame with approx 31,000 rows and 400 cols and I want to export to an excel sheet using write_xlsx
When I try this I get the following error:
write_xlsx(data, "FILEPATH")
[ERROR][libxlsxwriter/packager.c:1142]: Error in writing member in the zipfile
[ERROR] workbook_close(): Zip ZIP_ERRNO error while creating xlsx file 'FILEPATH'. System error = No error
Error: Error in libxlsxwriter: 'Zip generic error ZIP_ERRNO while creating the xlsx file.'
I think this error started when I inadvertently tried to open an Excel file that R was writing before it had actually completed. I have shut down R and restarted and also re-installed the writexl package to no avail.
The data i'm attempting to export is approx 150mb. When I try to write a smaller file (1.5mb) this works but when I try to open the excel file it says it is locked for editing by R and can open be opened 'read only'.
I have exported much larger data than this in the past with no issues so cannot figure this out, any help appreciated.
What OS are you using and is it possible that you are running out of free space in the tmp directory? – jmcnamara yesterday
I think you've cracked it. I had returned to work on Monday, ran the script again and, sure enough, it worked first time. Only difference is I had deleted some content from the directory I was working in because I had got a disk full notice!
I don't know write_xlsx but I would suggest a simple alternative as the following:
library(rio)
library(xlsx)
export(data, "exportname.xlsx")
However in your code might you need to add the file name as the following:
library(writexl)
write_xlsx(data, "FILEPATH// file name.xlsx")

I'm on RStudio, just wanting to read a csv file:
newdata <- read_csv("Nameofdata.csv",
col_names = TRUE)
But it keeps telling me that the file doesn't exist. It does exist. I'm staring DIRECTLY at it, underneath the file path that RStudio insists is wrong. I can open it in another tab, I can open in in excel, it's EXACTLY where RStudio says it's not existing. Please help.
Looking very closely at your screen shot, commenters are suggesting that you have an extra space at the beginning of your file name.
Also, I see that the working directory appears to be correct (the error message lists it as C:/users/mdavi/Desktop/School/Research/Sc, which appears to match what is listed in the Files pane
A couple of strategies for trouble-shooting file-locating problems:
use getwd() and list.files() to confirm your working directory and what files R can see from there (you can read this introduction to get more background on working directories):
use file.choose() to select a file interactively; it's generally a bad idea to use this in production code, as it will add an interactive step when you usually want to be able to run all of your code start to finish without needing manual steps, but it's quite useful for debugging.
If you wanted R to list files that approximately matched your specified filename, you could use
L <- list.files(pattern="*.csv")
agrep("myfile.csv", L, value=TRUE)
You need to set your working directly correctly, either via setwd("~/Desktop/School/Research/SC") in the R Console (that's what I think I see in your screenshot: ~ stands for your home directory, i.e "Users/Whoever") or via Session > Set Working Directory > To File Pane in the RStudio menus.
You can read a variety of Stack Overflow questions about setting the working directory for more complete context ... web searching on "R 'working directory'" might help too.
