    <p>I'm trying to work with R using a directory in my external hard drive as working directory. I can set the working directory to where I want, but when I use <code>list.files</code> R can't see anything. I also can't use <code>read.delim</code> to load a file.</p> <p>For example:</p> <pre><code>&gt; rm(list = ls()) &gt; WD&lt;-"../../../Volumes/My_HD/my_working_directory" &gt; setwd(WD) &gt; getwd() [1] "/Volumes/My_HD/my_working_directory" </code></pre> <p>So far so good, but then:</p> <pre><code>&gt; list.files(WD) character(0) </code></pre> <p>Whilst I would expect a list of the files that I know are there and that I can see and open with Finder and with the Terminal. Actually the R script itself is inside that directory. </p> <p>If then I try to open a file I get something like this:</p> <pre><code>&gt; myfile &lt;- read.delim(paste(WD,"/file_name", sep = ""), header = T) Error in file(file, "rt") : cannot open the connection In addition: Warning message: In file(file, "rt") : cannot open file '../../../Volumes/My_HD/my_working_directory/file_name': No such file or directory </code></pre> <p>I thought I was doing something wrong specifying the path to the directory, but I tried point and click from RStudio (Session>Set Working Directory and either >To Source File Location or >Choose Directory...) and got the same unhappy result. </p> <p>I'm using R version 2.15.1 on a MacBookPro (OS X 10.7.05). I'm running R from RStudio version 0.97.551, but the problem is not related to RStudio as it happens also when I try directly on R.</p> <p>Any help will be very much appreciated. Thanks.</p>

    1. COwhat does `list.files(getwd())` return after setting your working directory? I've found R to be a little touchy with relative paths, for reasons I don't understand.

    2. COIt's simple, your folder path is incorrect.

    3. CO@Peter `list.files(getwd())` gives me the desired list of files, but `list.files` alone keeps failing. Weird indeed. I suppose I will change my code to replace my WD directory object with getwd(). Thanks. Just for curiosity, @RomanLuštrik what is wrong in my path? I get the same if I try point and click from RStudio and

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.
