I need help fixing this code, please see attachedIn $[33]$: default$\_$model$\_$datadata$[$c$(\text{'}$age$\text{'},$ 'talach', $\text{'}$cp$\text{'},$ 'trestbps'$)]$

pred predict$($mode$12,$ newdata$=$default$\_$model$\_$data, type$=$'response'$)$

# If the predicted probability of default is $0\mathrm{.}50$ then predict target default $($default$=\text{'}1\text{'}),$ otherwise predict no target

# default $($default$=\text{'}{0}^{\text{'}})$

depvar$\_$pred $=$ as$.$factor$($ifelse$($pred $0\mathrm{.}5,\text{'}1\text{'},\text{'}\text{'}))$

# This creates the confusion matrix

conf.matrix table$($data$heart$\_$data, depvar$\_$pred$)[$c$(\text{'}{}^{\text{'}},1^{\text{'}}\text{'}),c{(}^{\text{'}}{}^{\text{'}},{?}^{\text{'}}{1}^{\text{'}})]$

rownames$($conf$.$matrix paste$("$Actual$",$ rownames$($conf$.$matrix$),$ sep $="$: default$=")$

colnames$($conf$.$matrix paste$("$Prediction$",$ colnames$($conf$.$matrix$),$ sep $="$: default$=")$

# Print nicely formatted confusion matrix

print $("$Confusion Matrix"$)$
