Hi Nolwenn,
Your suggestion helped. Thank you. I needed a forward-slash instead of
back-slash in the filepath.
> x <- read.FCS("C:/Documents and Settings/Owner/Desktop/Data/surface.002")
> summary(x)
Returns:
FSC-H SSC-H FL1-H FL2-H FL3-H FL2-A FL4-H
Min. 114 11.0 1.000 1.000 1.0 0.00 1.000
1st Qu. 328 109.0 2.867 1.000 113.9 0.00 4.705
Median 520 326.0 107.000 1.084 192.1 0.00 10.390
Mean 546 418.2 975.900 13.160 238.2 2.47 58.890
3rd Qu. 716 677.0 1728.000 2.574 329.7 0.00 18.650
Max. 1023 1023.0 8816.000 8203.000 7167.0 1023.00 10000.000
And also:
> read.flowSet(path="C:/Documents and Settings/Owner/Desktop/Data", package
= "flowCore")
Returns:
A flowSet with 14 experiments.
column names:
FSC-H SSC-H FL1-H FL2-H FL3-H FL2-A FL4-H
However, when I input:
fs <- read.flowSet(path="C:/Documents and Settings/Owner/Desktop/Data",
package = "flowCore"), name.keyword = "SAMPLE ID", phenoData = list(name =
"SAMPLE ID", Filename = "$FIL"))
It returns:
Error: unexpected ',' in "fs <- read.flowSet(path = "C:/Documents and
Settings/Owner/Desktop/Data", package = "flowCore"),"
When logic tells me that it should accept the comma and return:
[1] "name" "Filename"

Hi Steve,
Thank you for point at the error. We need to fix the released version of
flowViz (I get the same error and have the same package version). The
development version works if you really want to test the function but
you should be careful in mixing release and development versions as it
may generate new errors that might more difficult to track.
As for your second question if you want all the files from your "Data"
directory, this should work:
samp <- read.flowSet(path="C:/Documents and Settings/Owner/Desktop/Data")
Hope it helps,
Nolwenn
