Body
I'm new to R and so not very familiar to even simple functions yet. Short description of my attempt: I got one direktory with several subdirectories (11 subdirectories, as seen in the code below ). Each of this subdir. has got the same struckture. Each of this subdir. contains four .csv-files, called gwn,rh,ro and rg1. I want to read each of the gwn.csv one by one and write parts of it to another file, that has been created in my main morking folder. Thats my last try: <pre><code>files<-list.files("../Tagessummen") </code></pre> That gives me the structure of the direktory that looks like: <pre><code>[1] "Beobachtet" "Projektion_00" "Projektion_11" [4] "Projektion_22" "Projektion_33" "Projektion_44" [7] "Projektion_55" "Projektion_66" "Projektion_77" [10] "Projektion_88" "Projektion_99" </code></pre> Now i thougt i could use this for defining the loop-path. I tried with this: <pre><code>for(i in 1:length(files)) Grundwasserneubildung_Daten<-read.table('../Tagessummen/',files,'/zeit.dat/Tag/geb_sum.gwn') Grundwasserneubildung_Daten<-Grundwasserneubildung_Daten[-1,-1] Grundwasserneubildung<-cbind(Grundwasserneubildung,Grundwasserneubildung_Daten) end </code></pre> But it does not work. I think, it has something to do with the definition of the loop. I did read lots of similar questions, but nothig worked so far. 2nd questions wolud be, how to implement another loop, to read and work with the other three files in the same'one-by-one'-manner. Hope you got some enlightening answer for me.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
