The RExpression actor source entry is only a single line. It does not convert pasted newlines into in the XML.

Current the actor's XML has this bit:

<property name="expression" class="ptolemy.kernel.util.StringAttribute" value="a <- c(1,2,3,5) plot(a)">
<display name="R function or script"/>
</property>
<property name="_editorFactory" class="ptolemy.vergil.toolbox.TextEditorTableauFactory">
<property name="attributeName" class="ptolemy.kernel.util.StringAttribute" value="expression">
</property>
<property name="columnsDisplayed" class="ptolemy.data.expr.Parameter" value="80">
</property>
<property name="rowsDisplayed" class="ptolemy.data.expr.Parameter" value="40">
</property>
</property>

Replacing that bit of XML with the following, based on older RExpression actors, seems to work:

<property name="expression" class="ptolemy.kernel.util.StringAttribute" value="a <- c(1,2,3,5) plot(a)">
<display name="R function or script"/>
<property name="R Expression" class="ptolemy.actor.gui.style.TextStyle">
<property name="height" class="ptolemy.data.expr.Parameter" value="20">
</property>
<property name="width" class="ptolemy.data.expr.Parameter" value="80">
</property>
</property>
</property>
