Communicating with R

The applet parameter R is set for all the communication with R.

Applet parameters.

TITLE Set a title to display.

R Set the R code to pass onto a remote server for execution when the button is pressed.

VALUE Set an initial value to be read when it is called.

is created by the ISR style command:

\applet {comboBox}{sample}{width=240 height=25}
{TITLE="R version"; VALUE=""; R="@sample = R.version.string"}

Extension of R code. Before R code is passed down for execution, LaTeX style extension has to be preprocessed. This enables us to take advantage of applet-to-applet communications to exchange data between the applets.

@applet-name< applet-name has to be a textBox.class applet name. It redirects all the following text output to this textBox.class multiple-line display.

@applet-name= ... applet-name has to be a comboBox.class applet name. It sets a value in a single-line display of this comboBox.class if it has a place to display.

@applet-name:column-name= ... applet-name has to be a dataTable.class applet name. It sends an array data to column-name of this dataTable.class.

@applet-name:`[[column number]]`= ... (DEFUNCT) It set the column data specified by column number of the dataTable.class. It only work for code.R but it has no effect on e-stat.

... @applet-name ... applet-name has to be a comboBox.class applet name. It is replaced by a value (or an array data) in this comboBox.class.

... @applet-name:column-name ... applet-name has to be a dataTable.class applet name. It is substituted with the column data specified by column-name of this dataTable.class.

... @`applet-name` ... applet-name has to be a comboBox.class applet name. It replaces to the column name selected from the list of column names of databox at the comboBox.class.

... @applet-name:`[column number]` ... It is substituted with the column data specified by column number of this dataTable.class.
