library(TTR)
library(xts)
#main GUI code
win=gwindow( PREDICTIVE TRADER ,visible=FALSE)
group-ggroup(cont=win)
left_group-ggroup(cont=group,horizontal=FALSE)
right_group-ggroup(cont=group,horizontal=FALSE)
frame-gframe(widgets,cont=left_group,expand=TRUE)
size(frame)-c(400,450)
tbl=glayout(cont=frame)
tbl[7,1]= gbutton(BUYANDSELLSIGNALS ,cont=tbl,handler=BSS)
tbl[5,1]=glabel(ENTER SYMBOL:-,cont=tbl)
tbl[5,2]-gedit( , cont=tbl,coerce.with=as.character)
tbl[11,1]-glabel(ENTER PROFIT TARGET:-,cont=tbl)
tbl[11,2]= gedit(, cont=tbl,coerce.with=as.numeric)

tbl[13,1] =glabel(STOP LOSS TARGET:-)
tbl[13,2] =gedit(, container=tbl,coerce.with=as.numeric)
visible(win)=TRUE
}
I Didn't put the whole function handlers and the remaining
codesfor its lengthiness , my issue is the function is
showingsome problem like when i execute the function and

[R] acessing symbols dynamically through a gedit box using getsymbol function
I had tried a little weird way of accessing symbols from YAHOO.FINANCE in

tbl[5,2]=gedit(, cont=tbl,coerce.with=as.character)
BSS-function(h,...)
{
options(guiToolkit=RGtk2)
data - new.env()
getSymbols(svalue(tbl[5,2]),env = data, auto.assign = T)
options(getSymbols.warning4.0=FALSE)
ashdata1-data.frame(tbl[5,2])
}
My question is I could not get those symbols from the getSymbol function ,
can any one show me some way how to access this symbols dynamically ,such
that the users can specify any symbols and could access those data in a
click of a button .. Thanks You.
