r - produce multiple time series in different plot and save in working directory -

-

this appears quite simple have no idea how go it. dataframe looks this:

var1   var2  var3 var4 var5 var6 ..... var57  1     23    67   89   63   34   .....  90  2     34    43   43   23   23   .....  32  3     45    65   45   32   54   .....  43  4     45    32   18   61   87   .....  39  5     23    74   53   54   76   .....  54  6     21    65   34   34   12   .....  97  .     .      .    .    .    .   .....  .    .     .      .    .    .    .   .....  .    .     .      .    .    .    .   .....  .    365    54     78   54  12    90  .....  53

i want produce separate plots , save them in working directory var1 against variables.

plot(var1 ~ var2) plot(var1 ~ var3) plot(var1 ~ var4) plot(var1 ~ var5)      .      .      .      .      . plot(var1 ~ var57)

is there way automate dont have produce each individual plots @ time , save in working directory?

thanks lot.

pdf("plots.pdf") for(i in 2:ncol(df)) plot(df[,1] ~ df[,i]) dev.off()

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
