saveData: Write Data to a Local Location or to Dropbox
In mdsteiner/ShinyPsych: An easy way to program psychology experiments using Shiny

Take a list of a specified format and save it to the specified location. All elements in the list must be either of same length or of length 1 because as.data.frame will be called on the list. The file name is created by pasting partId, Sys.time(), digest(data) and the suffix (and of course the file specification .rds or .csv).

saveData(
  data,
  location,
  partId,
  checkNull = TRUE,
  addNameList = NULL,
  suffix = "_s",
  outputDir = NULL,
  droptoken = "droptoken.rds",
  asrds = FALSE,
  separator = ",",
  mailSender = NULL,
  mailReceiver = NULL,
  mailSubject = "ShinyPsych Data",
  mailBody = "Data attached..."
)

`data`	list. Contains all the data that should be saved.
`location`	string. The location to which data should be saved. Valid inputs are "local" , "mail" or "dropbox".
`partId`	string. The participant id. This will be pasted to the beginning of the filename. If no id should be part of the filename leave this, in this case a sample of length 9 from 1:9 will be drawn and used as first part of the filename.
`checkNull`	logical. If TRUE (default), each value in the list that is NULL will be replaced by NA.
`addNameList`	string. Vector with length of data containing the variable names that should be given to the data. If names should not be change just leave this as NULL.
`suffix`	string. The suffix given to the name of the saved file. You could e.g. use "_s" (default) for the survey data and "_g" for the game data to have an easy distinction in the filenames.
`outputDir`	string. Directory WITHOUT the file name in which to save the data.
`droptoken`	string. Name of the rds file with the dropbox acces tokens. If this file is not in the app directory the full directory must be given. Only needed if location is set to "dropbox".
`asrds`	logical. If TRUE (default is FALSE), data is saved as an rds file.
`separator`	string. Separator that should be used to write the file. Default is ",".
`mailSender`	string. Mail sender address. Passed to `sendmail` from the sendmailR package.
`mailReceiver`	string. Mail receiver address. Passed to `sendmail` from the sendmailR package.
`mailSubject`	string. The mail subject. Passed to `sendmail` from the sendmailR package.
`mailBody`	string. The mail body. Passed to `sendmail` from the sendmailR package.
