Download the Mailing List

The list of recipients for sending mailings can be downloaded as a CSV file under List of Contacts → Download Mailing List. CSV files can be opened in all common applications for data processing or spreadsheets (e.g., Excel, OpenOffice Calc, SPSS, …). The file is Unicode-formatted.

Data Columns in the File

The file always contains all of the following columns – regardless of whether the entries contain corresponding information.

A person ID that may have been assigned is not noted in the list, because the collected data would otherwise no longer be anonymous.

Data Import in R

When downloading the list of contacts, SoSci Survey provides a CSV file that is optimized for Excel (encoding UTF-16 Little Endian). To read the CSV file in R, the fileEncoding must be specified accordingly:

addresses = read.csv("panel.csv", sep="\t", quote = "\"", fileEncoding  = "UTF16LE")

If you omit this encoding, you get the following error:

Error in make.names(col.names, unique = TRUE) : 
  invalid multibyte string at '<ff><fe>
