microarray analysis for data in GSE160613 : how to compare data ?
I do not know how to make a comparison. And in R, I get this error: cont.matrix <- makeContrasts(antiVEGFR_antiVEGFA, levels=design)
Error in makeContrasts(antiVEGFR_antiVEGFA, levels = design) :
The levels must by syntactically valid names in R, see help(make.names). Non-valid names:
anti-VEGFA_1,
anti-VEGFR2_1,
Dual_2,anti-VEGFA_2,anti-VEGFR2_2
