Dear all,
I am using the following function so that user can input a numerical value.
readnumber<- function()
{
for(j in 1:10){
value=readline("enter the threshold for number of reads: ")
if(is.numeric(value)==T)
{return(value)
break}
else
print("wrong number Please enter numerical value ")}
}
But if by chance user tries to put character it will show the message-
wrong number Please enter numerical value
now when I am calling this function and entering numerical value,then also it
is showing the message-wrong number Please enter numerical value
Can you please tell me what mistake I am doing?
Thanking you,
Warm Regards
