Need help Fixing PCA Vectors

Hi,

I've already performed a principal components analysis (PCA) on the length measurements. However, I am having trouble producing a biplot that shows the skulls as points and measurements as vectors. My codes have the skulls as vectors and the measurements as points. Is there an easy way to switch these data points? I've attached my codes and a dput below. Thank you for helping.

CODES

#Log transform
Data1[,5:28] <- log(Data [5:28], 2)
#Keep length values
Data2 <- Data1
Data2 <- subset(Data2, select = c(museum, accession, species, forage, bcl, cbl, pl, fl, tl, zl, jl))
#Run PCA
Data2.pca <- prcomp(Data2[,c(5:11)], center = TRUE, scale = TRUE)
summary(Data2.pca)
#Scores
px <- scores(Data2.pca, choices = 1:5, display = "species", scaling = 0)
#Plot
biplot(Data2.pca, xlab="PC1", ylab="PC2", main= "PCA Plot")

Try the following code:

Import data

Data1 <- Data
#Log transform
Data1[,5:28] <- log(Data [5:28], 2)
Data1

#Keep length values
Data2 <- Data1
Data2 <- subset(Data2, select = c(species, bcl, cbl, pl, fl, tl, zl, jl))
Data2

#Run PCA
p <- prcomp(Data2[,c(2:8)], center = TRUE, scale = TRUE)
s <- summary(p)

Screeplot

layout(matrix(1:2, ncol=2))
screeplot(p)
screeplot(p, type="lines")
par(mfrow = c(1,1))

Show PC1 and PC2 data

to plot different PCs, change the numbers

p$x[,1:2]

See importance

s$importance

Create groups

pch.group <- c(rep(21, times=23), rep(22, times=67), rep(23, times=41), rep(24, times=16))
col.group <- c(rep("blue", times=23), rep("purple", times=67),rep("red", times=41), rep("green", times=16))

Plot individuals

plot(p$x[,1], p$x[,2],
xlab=paste("PCA 1 (", round(s$importance[2]*100, 1), "%)", sep = ""),
ylab=paste("PCA 2 (", round(s$importance[5]*100, 1), "%)", sep = ""),
pch=pch.group, col="black", bg=col.group, cex=2, las=1, asp=1,
xlim= c(-4,4),ylim= c(-9,6), main= "PCA Plot")

pch = symbols

cex = symbol size

bg = background colors

las = orientation of axis labels

asp=1 esnusres axes are same scale

Add grid lines

abline(v=0, lty=2, col="grey50")
abline(h=0, lty=2, col="grey50")

Add labels

#text(p$x[,1], p$x[,2], labels=row.names(p$x), pos=c(1,3,4,2), font=2)

Get co-ordinates of variables (loadings), and multiply by 10

l.x <- p$rotation[,1]*10
l.y <- p$rotation[,2]*10

Draw arrows

arrows(x0=0, x1=l.x, y0=0, y1=l.y, col="red", length=0.15, lwd=1.5)

Label position

l.pos <- l.y # Create a vector of y axis coordinates
lo <- which(l.y < 0) # Get the variables on the bottom half of the plot
hi <- which(l.y > 0) # Get variables on the top half

Replace values in the vector

l.pos <- replace(l.pos, lo, "1")
l.pos <- replace(l.pos, hi, "3")

Variable labels

text(l.x, l.y, labels=row.names(p$rotation), col="red", pos=l.pos)

Add legend

legend("bottomleft",
legend=c("A. cinerea ", "E. lutris ", "L. canadensis", "P. brasiliensis"), col="black",
pt.bg= c("blue","purple","red","green" ),
pch= c(21,22,23,24),
pt.cex=1.5)
