[sidra]

hi,
i know that to access ceratin variables from data frame i need to use $,
like this
Frames<-filename$Frames
Now i have 30 colums and i als0 want to save them in the same named variables.

S001_Ang_278<-filename$S001_Ang_278
S002_Ang_420<-filename$S002_Ang_420
S003_Ang_422<-filename$S003_Ang_422
S004_Ang_278<-filename$S004_Ang_278
S005_Ang_420<-filename$S005_Ang_420
.... till S030Ang_420<-filename$S030_Ang_420
i dont know how to loop over them

The simplest way to do this is with

attach(name_of_your_data_frame)

The columns will be separately available, but they will not show up with ls().
