Rstudio read csv file leading to the last column/variable in NA


I’ve got an issue during reading csv file using Rstudio (both latest versions). After importing data into Rstudio, all values of the last column/variable became NA. When reading the same data using R, data showed normally. When I converted the data set to RData file, Rstudio showed data normally.
Does anyone know the reason why?

Much appreciate any your comments and suggestions.

Are you using read.csv? What messages do you get? Probably you just have an extra column in your data file.

Thanks Woodward and Andres,

I found that Rstudio use read_csv() that read csv flies in incorrect way.
I typed read.csv() in Rstudio environment as usually use in R software, it shows results normally.

I think that read_csv() from menu bar have had an issue that needs to be considered.

Kind regards,

I usually use read_csv() in a script. Sometime I need to fiddle with the options to get the right result.

read.csv and read_csv are slightly different.
