Please help me for rechecking them. Thank you.

The error messages you are showing have nothing to do with package installation problems but with you referencing objects that do not exist in your current working environment, can you check and clarify what your problem actually is?

Thank you very much for your comment. I can already amended error code in library (boot). Later, the codes can run the normal result.

Loading package "boot" (Functions for bootstrapping)

library(boot)

Creating Function to obtain R-Squared from the data

r_squared <- function(formula, data, indices) {
val <- data[indices,] # selecting sample with boot
fit <- lm(formula, data=val)
return(summary(fit)$r.square)
}

Performing 299 replications with boot

output <- boot(data=heart_failure_clinical, statistic=r_squared,
R=299, formula=DEATH_EVENT~serum_creatinine+anaemia)
