Hi Dan,
<div class=""><br class="">
</div>
<div class="">Your script misspecified the label referring to base image in the generateCI2IFC function and the list that combines both cis. In the development version (version 0.2.6) I have added user feedback to the package, so rcicr will give you a more
informative error message that will help find this mistake.</div>
<div class=""><br class="">
</div>
<div class="">Moreover, up until the current version, if you want images aggregated across subjects, you need to feed aggregated data into the generateCI2IFC. Otherwise the data structures become to big and R will crash with an error message. This is what will
happen if you run the code below with your current version. However, I adapted generateCI2IFC do this automatically for you in the development version (version 0.2.6), so you don't have to do the aggregation yourself. The function will simply assume it can
aggregate data that is fed into it by stimulus number. If you just provide the data for a single subject, the behavior will be the same as previously.</div>
<div class=""><br class="">
</div>
<div class="">I have uploaded the development version to R-Forge and it is being built as we speak. You can see its current status at <a href="https://r-forge.r-project.org/R/?group_id=1932" class="">https://r-forge.r-project.org/R/?group_id=1932</a>. As soon
as its ready (status: current), you can follow the instructions on <a href="http://ron.dotsch.org/rcicr" class="">
http://ron.dotsch.org/rcicr</a> to install the development version. Then you should be able to run the following code without problems:</div>

<div dir="ltr" class="">Thanks, Ron. I saw the error after I sent the email. However, after accounting for it, I still get the same colMeans error. That is, I seperated the data by base image and tried call the batchGenerateCI2IFC function again with no success.
Do you have any idea what variable this the colMeans(weighted) is referring to?

<div class="">This is a bit complicated, because it depends on how you structured your data file and whether the different base images were presented to the same participants or to different ones. Anyway, you have made a mistake in your code. Your reference
baseimage as argument to the call to batchGenerateCI2IFC but you define the two baseimages as separate variables earlier (baseimage1, baseimage2). For now, the easiest option is to only refer to one as baseimage, and make sure you then only supply the subset
of responsedata that applies to that specific base image.</div>
