Error in data.frame

[jamesboot]

Hi, thanks for developing such a great package. When I perform clustering and then try to visualise the clustering using plotCluster I get an error:

Error in data.frame(..., check.names = FALSE) : 
  arguments imply differing number of rows: 20, 0

Code used to perform clustering and plot is below:

set.seed(1)
cyt <- runCluster(cyt, cluster.method = "kmeans", k = 20)
cyt <- updatePlotMeta(cyt)
plotCluster(cyt, item.use = c("tSNE_1", "tSNE_2"), category = "categorical",
            size = 20, show.cluser.id = TRUE)

Thanks in advance
