R Documentation

Does the reverse of convertDFtoDB: converts a data.frame of converted data back to its original data.frames. Each row from the provided data.frame (df) is converted to a separate data.frame

Description

Does the reverse of convertDFtoDB: converts a data.frame of converted data back to its original data.frames. Each row from the provided data.frame (df) is converted to a separate data.frame

Usage

convertDBtoDF(
  df,
  columnNames = colnames(df),
  restoreClasses = FALSE,
  collapseChar = ";",
  vectorClass = "integer",
  fromBlob = TRUE,
  type = "gzip"
)

Arguments

`df`	data.frame to be converted
`columnNames`	character vector specifying which columns from the df argument are to be put in the converted data.frame(s)
`restoreClasses`	default is FALSE. IF TRUE then the first row of the data.frame argument (df) must contain the classes (as character vectors) to be used for the columns
`collapseChar`	the character to be used as seperator
`vectorClass`	class of the seperate elements, default = "integer". Other tested options are "numeric" and "character". Note: all columns are the same class when vectorClass is a single element vector. The argument can be different types, but then all column types need to be specified, eg c("numeric", "integer")
`fromBlob`	is the data raw datatype or not
`type`	character string, the type of compression. See ?memCompress for details
