I have the following R code for creating barplot:

# ... here I read cvs file

mx <- rbind(results$"AVG.P10.")   
colnames(mx) <- results$"RUN"    
rownames(mx) <- "AVG P"    
barplot(mx, beside=T,  col=c("grey"), names.arg= results$"RUN", 
        cex.axis = 1.5, cex.lab=1.5)

I have tried cex.lab=1.5 but it does not work at all.

According to ?barplot, you need to use cex.names=1.5.

barplot(mx, beside=TRUE, col=c("grey"), names.arg=results$"RUN", 
        cex.axis=1.5, cex.names=1.5)
