Dear Users,
I'm trying to build a scatter plot for the first time using this script:
pairs(~pH+Oxygen+Salinity+Temperature+Eh+Water_Level+Fe_total+FeII+V, data=RT2, lower.panel=panel.smooth, upper.panel=panel.cor, pch=10, main="")
panel.cor <- function(x, y, digits = 2, prefix = "", cex.cor, ...)
{
usr <- par("usr"); on.exit(par(usr))
par(usr = c(0, 1, 0, 1))
r <- abs(cor(x, y, method = "spearman"))
txt <- format(c(r, 0.123456789), digits=digits)[1]
txt <- paste(prefix, txt, sep = "")
if(missing(cex.cor)) cex.cor <- 0.8/strwidth(txt)
text(0.5, 0.5, txt, cex = cex.cor)
}
Could you please tell me how to increase the font size of my parameters and font size of correlation factors?
Do you think if it is possible to title x- and y- axes?
Thank you in advance!
