![]() ![]() Here is an example, of some code that fixes the “cannot open the connection” error message. As a result, the program cannot find the file and it returns our error message. If you look at the load function, you will notice that the filename is not spelled correctly. In this example, we first create a data file, so there is a data file to load if the code is entered properly. > save(list = c(“df1”, “df2”, “df3”), file = “test1.rda” )Įrror in readChar(con, 5L, useBytes = TRUE) : cannot open the connectionĬannot open compressed file ‘test.rda’, probable reason ‘No such file or directory’ ![]() Here is an example of some r code that causes the “cannot open the connection” error message. Once you have loaded the data file you will get all the variables it contains, and you can apply analytical tools like the plot function to it. ![]() Fixing the problem is a matter of making sure that the file has the correct name and is where your program is looking for it. You could have received it in a previous message from someone, but never actually downloaded it. It can occur because you have miss-typed the filename, file extension, or some part of its path. This can occur because the file is part of a package that you have not installed or that it is from a different r version. The “cannot open the connection” error message occurs when you are trying to read a data file that your program cannot find. Fixing it requires, making sure that the data file exists where it is supposed to, and that you are calling the correct filename. This can occur because you have the wrong filename, because the data file is someplace else, or simply does not exist on your system. When working in R studio you will get the “cannot open the connection” error message if you try to read a data file that is not there. ![]()
