[יניב לוי‎]

,hi to all

i am trying to use "par" command - to see 2 charts together : 

(  attach(htr2         

(  par(mfrow=c(1,2)   

((  print(  barchart(year ~ y_kayam , groups=shlav, htr2, auto.key = list(columns = 2)    

("  plot(table (  htr2$y_mevukash , htr2$shlav  ) , ylab = "a yhd" , xlab="a shlav
