# trio plots of box-cox transformed predictors

# (boxplot, histogram, qqplot)

```
for(i in 1:11){
v <- paste("x",i,sep="")
par(mfrow = c(1, 1))
boxplot(df6[[v]],xlab=v,main="Boxplot of bc transformed data")
hist(df6[[v]], main="Histogram",xlab=v)
qqnorm(df6[[v]],ylab="Sample Quantiles",xlab="box-cox transform(quality)")
qqline(df6[[v]])
}
```

Interesting stats

min(df6$x1) = 1.335

max(df6$x1) = 2.766

min(df6$x4) = -0.511

max(df6$x4) = 4.187

Error messages center around illegal ylim values but what causes these errors, how do I see what code is being generated ?

Error in plot.window(...) : need finite 'ylim' values

In addition: Warning message:

In bplt(at[i], wid = width[i], stats=z$stats[,i], out=z$out[z$group==:

Outlier (-Inf) in boxplot 1 is not drawn
