flowCore | Core flow cytometry infrastructure | Theme library

I am trying to set the x limits on a ggcyto(ggplot2) plot, but it doesn't seem to work. The x-limit that I set is squished all the way to the right and there is a lot of empty space. Not sure what else to try. I tried setting biexp scale but it looked the same.

I work with the package flowCore found in Bioconductor, which reads my data files in an S4 class format. You can type library(flowCore) and then data(GvHD) which loads an example dataset. When you type GvHD you can see that this dataset is made out of 35 experiments, which can be accessed individually by typing for example GvHD[[1]].

Now I am trying to delete two columns FSC-H and SSC-H from all the experiments, but I have been unsuccessful.

I have tried myDataSet<- within(GvHD, rm("FSC-H","SSC-H")) but it doesn't work. I would greatly appreciate any help.

I have a directory containing 28 FCS files (raw data from a flow cytometer). I am converting the list of 'flowFrame' objects into a list of data frames, and I would like to create a column in each data frame that refers to the file name.
