ENVISIONQuery.chunk(ids, utilityTool, service, tool, formatIt,
    options=list(), filter=list(), compact=TRUE, writeHTML=FALSE,
    nchunk=NA, verbose=FALSE, ...)

`ids`	Character vector representing the ID list.
`utilityTool`	The tool used to convert the ID list into the input Enfin xml file.
`service`	Service handler
`tool`	The tool used to perform the conversion
`formatIt`	If TRUE (default), try to interpret the returned character table and structure the result. If false, the character string representing the entire enfinXML file returned by ENVISION.
`options`	The (optional)list each element of which represents the <name,value> pair used to apply the additional constraints when sending a query to a particular service (maximum number of pathways for Reactome service as an example)
`filter`	The list where the name of each element represents an output data frame column on which filetering is to be performed ('organism.species', 'Microarray.platform' etc.) and the element itself containing a character vector defining the set of values on which the merging (intersection) for a given column will be performed ('Homo sapiens' for 'organism.species', 'affy_hg_u133_plus_2' for 'Microarray.platform' etc.). The filtering is performed if the list is not empty and the formatIt=TRUE. Default is an empty list.
`compact`	If TRUE and the formatted output (formatIt = TRUE)is represented by a data frame, collapses the rows with duplicated match sets but different attributes into a single row with unique match set and an attribute list separated by comma for each attribute column. Default is TRUE.
`writeHTML`	If TRUE, write the received intermediate HTML to file. Default is FALSE.
`nchunk`	Chunk number. If not NA and writeHTML is TRUE the input and output xml file names are appended with chunk number. Default is NA.
`verbose`	If TRUE, enables diagnostic messages. Default is FALSE.
`...`	additional arguments.
