setArgsList(filename, env, isFile = TRUE, init = TRUE)
whatDeli(delimiter)
getMoreArgs()
assignArgs(value, env)
getArgs(env)
assignShowNum(value, env)
getShowNum(env)
assignCState(value, env)
getCState(env)
assignColInfo(value, env)
getColInfo(env)
setColInfos(types, env)
changeState(canvas, backBut, nextBut, env, forward = TRUE, endBut, viewBut)
setNewState(env, backBut, nextBut, forward = TRUE, endBut, viewBut)
addArgs(env)
dropArgs(env)
setSkip(widget, env, state = "state1")
moreArgs(env)
dropColumn(index, env)
setColName(index, entryBox, env)
setColType(index, entryBox, env)
assignLineData(lineData, env)
getLineData(env)

Arguments

filename filename a character string for the full name of a file
env env an R environment object for storing information
delimiter delimiter a character string for the delimiter whose letter representation is sought
value value a character or numerical value to be assigned to a variable
backBut backBut a tkwin object for the button that shifts back to the previous state
nextBut nextBut a tkwin object for the button that shifts to the next state
forward forward a boolean indicating the direction of state change
widget widget a tcltl widget
state state a character string for the state of importing process
index index an integer for the index of the list for column information
entryBox entryBox
canvas canvas a tcltk canvas
types types a vecter of string indicating the types of data columns
lineData lineData a vector of character strings read in using readLines
endBut endBut a tkwin object for the button that ends the process when pressed
viewBut viewBut a tkwin object for the button that refresh the window when pressed
init init a boolean that is TRUE when the widget is first set up and FALSE otherwise
isFile isFile a boolean that is TRUE if fileName is a file

Details

setArgsList calls function guess.sep to figure out the the header, sep, and data type of a file and sets the values for argument list and colInfo.

whatDeli gets the word representation of delimiters (e.g. tab for "t").

getMoreArgs generates a widget using widgetTools to collect some of the arguments for read.table.

assignArgs updates "argsList" stored in a predefined environment.

getArgs Gets "argsList" from a predefined environment.

assignShowNum Updates the value for "showNum" (number of rows to show in the interface.

getShowNum Gets the value for "showNum" (number of rows to show in the interface.

link{assignCState} Updates the value of "currentState" that is stored in a predefined environment.

getCState Gets the vlaue of "currentState" that is stored in a predefined environment.

assignColInfo Updates the values of "colInfos" (column information) that is stroed in a predefined environment.

getColInfo Gets the values of "colInfos" (column information) that is stroed in a predefined environment.

setColInfos Creates colInfo objects and sets the value of 'colInfos' list.

changeState changes the state and thus the interface of a widget.

\ling{setNewState} sets the state of a importing process.

addArgs adds a new state to the argument list for states.

dropArgs removes a state from the argument list for states.

setSkip Sets the value for the number of lines to skip when readling a data file.

moreArgs Gets some of the arguments for importing data using read.table.

dropColumn Sets the index values for data columns that are going to be droped when read using read.table.

setColName Sets the column names for a data file by getting column names from correct entry boxes.

setColType Sets the column type for a data file by getting column type information from correct entry boxes.

Value

whatDeli returns a character string.
getMoreArgs returns a list of arguments.
getArgs returns a list of the arguments for read.table.
getShowNum returns an integer for the number of rows to show.
getCState returns a character string for the current state.
getColInfo returns a colInfo object contains column information.

Note

The functions are part of the Bioconductor project at Dana-Farber Cancer Institute to provide Bioinformatics funcitonalities through R
