Here is my code:
library(caret)
set.seed(32343)
modelFit = train(type~.,data=training, method='glm')
It’s pretty standard but I am getting the error message:
Error in library(e1071) : there is no package called ‘e1071’
What’s the cause, and how can the problem be resolved?

You need to install the package e1071, as the error message is telling you.
install.packages('e1071', dependencies=TRUE)

If you will be using the caret package regularly try:
install.packages('caret', dependencies = TRUE)
This will automatically download package e1071 as well as ellipse and many other package dependancies that arise in using caret
for more information please check out the CRAN package page for caret

The “error: package e1071 is required” error message occurs when using the caret package. It is an r programming package that is dependent on the e package. This error message occurs when the e1071 package is missing. Fixing this error message is a simple matter of installing the e1071 package. This makes it a simple problem to fix.
Description of the R Error
Caret is a machine modeling model r package used to tune models by using training data. It uses algorithm and function processes on the data, in the modeling process. No matter what version of caret you are using, you need the same dependency packages to run the package properly. Our error message is triggered by the missing e package because the program cannot continue without it. This makes this error message basically a glorified file not found error message. It is easy to understand but easy to fall into because it is not your mistake. Fortunately, this error message is clear enough that it is easy to understand what is going on.
Explanation of the R error
The carrot package uses a support vector machine to work out the regression and classification. A support vector regression is a form of machine learning that uses latent class analysis. The support vector algorithms use md sums to produce the svm model. All of these require the e1071 to work, and so if it is not present, it produces our error message. This is an unusual circumstance because packages usually include any other packages upon which they are dependent. It most likely means that you accidentally unclicked the install dependency checkbox when you installed the caret. This resulted in the e package being accidentally left out of the installation list.
How to fix the R error
This is a simple error message to correct. All that you need to do is to install the e1071 package. To do so go into r studio then click on the Packages tab in the lower right-hand window. Under that click on the install tab. Next in the popup window that opens enter e1071 into the packages text box, and make sure the install dependency checkbox is checked. This will install the needed packages and fix the problem causing our error message. This is a fairly simple process, but it fixes the problem, and you will not get this error message again.
This is an easy-to-understand error message and an easy one to fix. In the process of installing the e1071 package, it is important to make sure that the install dependency checkbox is indeed checked. If you do not correct this, you will get similar errors in the future. The good news about this error message is that once you install any needed packages, the problem will be fixed for good.
Describe the bug
Training script fails with the error:
Error: package e1071 is required
Execution halted
As far as I can tell I am not using any function from e1071, and so it was not included in the cran_packages option to estimator. Adding "e1071" to cran_packages works around the issue.
To Reproduce
https://github.com/revodavid/azure-ml-R-tutorial/tree/77f1f5b34d033764c410ef78921a1d46767a843f
Expected behavior
If e1071 is always required, it should be loaded by default or documented as such. It’s an odd dependency to have.

I wish to install the VIM package for imputing some missing data in RStudio but I am getting an error with the related e1071 package.
The VIM package installs O.K. but the related e1071 fails for the following reason:

It looks like you got stuck in between a CRAN update of the e1071 package. When your R session asked what version of e1071 was current, it reported (and cached) version 1.6-7; however, soon after version 1.6-8 was uploaded to CRAN. Because of that, the R session attempted to download 1.6-7, but failed as only 1.6-8 was then available.
Restarting R should clear the local package listing cache and get you on your way.

Что мне нужно сделать, чтобы установить этот пакет?
Лучший ответ:
Похоже, вы застряли между обновлением CRAN пакета e1071. Когда ваша сессия R спросила, какая версия e1071 была текущей, она сообщила (и кэшировала) версию 1.6-7; однако вскоре после того, как версия 1.6-8 была загружена в CRAN. Из-за этого сеанс R попытался загрузить 1.6-7, но не смог, так как тогда было доступно только 1,6-8.
Перезапуск R должен очистить локальный кеш-лист и доставить вас на ваш путь.
