How do I get rid of the package e1071 installation error?

Question

I am trying to run the confusionMatrix function but it shows this error and when I try to install the package it shows the error in bold below it.

Error: package e1071 is required Traceback:

1. confusionMatrix(factor(test_data$area, levels = 1:100), factor(test_data$pred_rf, . levels = 1:100))
2. confusionMatrix.default(factor(test_data$area, levels = 1:100), . factor(test_data$pred_rf, levels = 1:100))
3. getFromNamespace("confusionMatrix.table", "caret")(classTable, . positive, prevalence = prevalence, mode = mode)
4. requireNamespaceQuietStop("e1071")
5. stop(paste("package", package, "is required"), call. = FALSE)
