R help - Nov 2010 - trouble with plotting data- possible bug?

Hi all,

When I write out some values and then use 'plot' and 'lines'
respectively I
can get R to plot me two lines. However when I get the data from a csv file
and run it I only manage to get one line running (whichever was invoked
first). The sample files are attached below and I've reproduced the code
below with the suspicious part marked as #??? (not even sure if thats
actually whats wrong).

Thanks in advance.
Sachin

A<-read.csv("small_table.csv", stringsAsFactors = FALSE);
A$period[nchar(A$period)==5]<-paste("0",A$period[nchar(A
$period)==5],sep="");
A$period<-as.Date(strptime(A$period,("%y%m%d")));

#get all unique names
name<-unique(A$LEVEL);

#create a table for each manager for discount_count_percentage
level=6;
month<-as.numeric(A$Month[A$LEVEL==name[level]]);
month3<-as.numeric(A$Month3[A$LEVEL==name[level]]);

period<-A$period[A$LEVEL==name[level]];
#???why is this part going wrong?
plot(period, month, type='l');
lines(period, month3, col=2);

p.s. sorry about corporate notice
