    <p>I have written a function that creates a barplot. I would like to save this plot as a pdf as well as display it on my screen (x11) when applying this function. The code looks like this.</p> <pre><code>create.barplots &lt;- function(vec) { x11() # opens the window ### Here is a code that creates a barplot and works perfectly ### but irrelevant for my question dev.copy(pdf("barplots.table.2.pdf")) # is supposed to copy the plot in pdf # under the name "barplots.table.2.pdf" dev.off() # is supposed to close the pdf device } </code></pre> <p>This creates the following error: 'device' should be a function</p> <p>When I modify the code to:</p> <pre><code>create.barplots &lt;- function(vec) { x11() ### Here is a code that creates a barplot and works perfectly ### but irrelevant for my question dev.copy(pdf) # This is the only difference to the code above dev.off() } </code></pre> <p>R displays the plot and creates a file called Rplots.pdf. This is a problem because of several reasons.</p> <p>I also tried to open the devices the other way around. First open the pdf device, than copy the content of the pdf device into the x11 device, than set the pdf device as active and than close the pdf device. The code here looks like this:</p> <pre><code>create.barplots &lt;- function(vec) { pdf("barplots.table.2.pdf") # open the pdf device ### Here is a code that creates a barplot and works perfectly ### but irrelevant for my question dev.copy(x11) # copy the content of the pdf device into the x11 device dev.set(which = 2) # set the pdf device as actice dev.off() # close the pdf device } </code></pre> <p>The problem here is that the wondow that is supposed to display the plot is empty!</p> <p>To sum up, I have two questions: 1) How to save a plot as pdf and display it in x11 simultaneously? And 2) How to save the plot not in the working directory somewhere else?</p> <p><em>EDIT</em></p> <p>The solutions above work great. But I still do not understand why</p> <pre><code>pdf("barplots.table.2") barplot(something) dev.copy(x11) </code></pre> <p>displays an empty grey window instead of copying the content of the pdf device in the window device! I also tried</p> <pre><code>pdf("barplots.table.2") barplot(something) dev.copy(window) </code></pre> <p>In which I failed as well...</p>

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.
