For the statistical file connector, the vendor and driver name is stat-direct. tdc file is an XML file that applies to a single data source and contains vendor and driver name information of the data source provider. If you need to use a different character set when reading from a statistical file, you can create a Tableau data source customization (TDC) file and specify the encoding to use. For example, if a colleague sends you a statistical file with Greek character encoding, then you must specify a Greek character set to use the file with Tableau. Sometimes, you might need to specify a different encoding. R files typically use the character encoding of the operating system, compared to SAS and SPSS files, which include the character encoding information in the file. Tableau reads the data in a statistical file (for example, an SAS or R file) based on the file's character encoding or on information in an input file. Change the character encoding for a statistical file You must decompress files first with another program, such as Gzip or WinZip, before you connect with Tableau. Tip: To quickly see documentation for this function, type "?save" at the command prompt.Ĭompressed files are not supported in Tableau Desktop.

In this case, you can use RStudio to save the file to a binary format, as follows: rda file with ASCII format, you’ll see an error saying, "Unable to read from file the table '' '.' does not exist". Tableau supports R data files that use binary format.ĪSCII format files are not supported in Tableau Desktop. Note that if the R data file contains more than one object, Tableau will connect to the first one. R data files should contain only one of the following types of objects: For more information, see Change the character encoding for statistical files. You can change the character encoding for a statistical file. To check for hidden objects, run ls(environment(), all.names=TRUE) from RStudio. R files may contain hidden objects in what appears to be a clean workspace. If an error message appears, "An error occurred while communicating with the data source," make sure that your statistical file contains only one object, and that the object is a data frame or a matrix. The Statistical File connector supports only one table per statistical file. The Statistical File connector does not support value labels.

Here is an example of a statistical file data source using Tableau Desktop on a Windows computer: Select the sheet tab to start your analysis.įor information about connecting to more than one table, see Join Your Data. For example, use a data source naming convention that helps other users of the data source figure out which data source to connect to. (Optional) Select the default data source name at the top of the page, and then enter a unique data source name for use in Tableau. On the data source page, do the following: Start Tableau and under Connect, select Statistical File, select the file that you want to connect to, and then select Open. Make the connection and set up the data source Use a different compression scheme to make the file readable for Tableau. Note: As of version 2020.1, Tableau no longer supports statistical files compressed with SASYZCR2. Tableau connects to SAS (*.sas7bdat), SPSS (*.sav), and R (*.rdata, *.rda) data files.
