Answer 3

Typically an encoding issue. You can try to change encoding or else deleting the offending character (just use your favorite editor and replace all instances). In some cases R will spit the char location, for example:

Not sure if this helps, just had a similar issue which I solved by removing " from the csv I was trying to import. The first row of the database had the column names written as "colname","colname2","etc" and I removed all the " and the csv was read in R just fine then.

Answer 5

You need to specify the correct delimiter in the sep argument.

I found this problem is caused by code of file, and I solved that by opening it with Windows note, saving with UTF-8, and reopening with Excel(it became garbled at first), and resaving with UTF-8, then it worked!
