    <p>The problem I am having is that every time I try to plot my points onto a map it seems to remove them.</p> <pre><code>#getmap library(ggplot2) library(ggmap) testmap &lt;- get_googlemap(c(lon=135,lat=-32) ,zoom=6, xlim=c(127,142), ylim=c(-23,-34)) save(testmap, file="test.rda") #Load file load(file="test.rda") #plot plotvar &lt;- c("V37","V39") plotdata &lt;- WellDownload[plotvar] #plotting ggmap(testmap) + geom_point(aes_string(x=plotdata$V37, y=plotdata$V39), data=plotdata, colour="red", size=3) </code></pre> <p><code>Removed 10001 rows containing missing values (geom_point).</code></p> <p>is the error I get, my database does have missing values but I don't understand why values are being removed.</p> <p>What I am aiming to do is to plot points on a map then later do an extrapolation of the data onto the maps based on the coords. I just wanted to find out why I was getting these errors, I have the txt file for the database but am not sure how to upload it.</p> <p>EDIT hopefully this should work <a href="https://www.dropbox.com/s/4rv52deuehyfn9l/WellDownload.txt" rel="nofollow">https://www.dropbox.com/s/4rv52deuehyfn9l/WellDownload.txt</a> here is the file</p> <p>Edit: I just tried a different method of accessing the data and its not removing rows anymore but says <code>"Discrete value supplied to continuous scale"</code>.</p> <pre><code>#load file load(file="e:/CameronFurness/xml_data/test.rda") #data mydata &lt;-data.frame(x&lt;-newdata[,"V37"],y&lt;-newdata[,"V39"],#lon= V37, lat=V39, col = NA_real_) #plot ggmap(testmap) + geom_point(aes(x, y), data=mydata, size=3, alpha=0.5, colour="red") </code></pre> <p><code>newdata</code> is a data frame I made with columns <code>V37</code> and <code>V39</code>. The coords I am using are in the file, they are <code>decimal_long</code> and <code>neg_decimal_lat</code>.</p>

    1. COI can sort of duplicate your error by creating some fake data which tries to plot results that are outside the plotting area. Of course it's impossible to directly address your real question without your data, but I'd try expanding your xlim and ylim and see if that helps.

    2. COHi cheers for the response, I have tried to increase the xlim,ylim but I think its got something to do with the dataset itself even though I tried to ignore or fill missing values

    3. COInstead of posting 55 columns of data, how about you post just the two columns you are using? You could also probably post just 10 rows. Then you can use `dput` to post the data directly into the question and everyone is happy.

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.
