Thank you!
It seems the flowViz (splom) error doesn't occur when I run R-flowCore
from My MacBook Pro setup (OSX 10.5.6):
> sessionInfo()
R version 2.8.1 (2008-12-22)
i386-apple-darwin8.11.1
locale:
en_CA.UTF-8/en_CA.UTF-8/C/C/en_CA.UTF-8/en_CA.UTF-8
attached base packages:
[1] tools tcltk stats graphics grDevices utils datasets
[8] methods base
other attached packages:
[1] flowViz_1.6.1 latticeExtra_0.5-4 lattice_0.17-17
[4] RColorBrewer_1.0-2 flowCore_1.8.1 Biobase_2.2.1
[7] feature_1.2.0 ks_1.5.10 mvtnorm_0.9-4
[10] rpanel_1.0-5 KernSmooth_2.22-22 rrcov_0.4-07
[13] robustbase_0.4-5
loaded via a namespace (and not attached):
[1] AnnotationDbi_1.4.2 DBI_0.2-4 MASS_7.2-45
[4] RSQLite_0.7-1 cluster_1.11.11 geneplotter_1.20.0
[7] graph_1.20.0 grid_2.8.1 stats4_2.8.1
---
yet it continues to produce an error from XP (sessionInfo contained in
previous email).
Also, with respect to the email just previous to this one; which
annotation do I use to plug a MacBook Pro OSX filepath into:
amp <- read.flowSet(path="C:/Documents and Settings/Owner/Desktop/Data")
The OSX filepath, as far as I can tell is "Macintosh HD/Users/stevan/
Desktop/Data".
Cheers,
Steve
