Hi,
I received the below error message when I was creating a flowSet consisting of two .lmd files.
Error in names(from) <- paste("V", seq(1, length(from)), sep = "") : 'names' attribute [2] must be the same length as the vector [0]
My entire workscreen is as follows,
Loading required package: flowCore > library(flowCore) > library(flowViz) Loading required package: lattice > x <- read.FCS("G://FCM files/JennyG4a23052015.LMD") Warning message: No '$PnE' keyword available for the following channels: 6 Using '0,0' as default. > x flowFrame object 'JennyG4a23052015.LMD' with 50000 cells and 6 observables: name desc range minRange maxRange $P1 FL3 FL3 Fluorescence 1024 1.009044 10000 $P2 EV Electronic Volume 1024 0.000000 1023 $P3 FL1 FL1 Fluorescence 1024 1.009044 10000 $P4 FL2 FL2 Fluorescence 1024 1.009044 10000 $P5 SS Side Scatter 1024 1.009044 10000 $P6 TIME Time 1024 0.000000 1023 383 keywords are stored in the 'description' slot > frames <- lapply(dir(system.file("G://FCM files/JennyG4a23052015.LMD", "G://FCM files/JennyG4b23052015.LMD", + package="flowCore"), full.names=TRUE), + read.FCS) > as(frames, "flowSet") Error in names(from) <- paste("V", seq(1, length(from)), sep = "") : 'names' attribute [2] must be the same length as the vector [0] Thank you in advance! |
