Hi all,

I was trying to install "S4Vectors" using "BiocInstaller" on R-3.5.1

But it gives error as "eval_utils.c:33: error: 'for' loop initial declarations are only allowed in C99 mode".

And It seems not to be a general problem.

Does anyone else encounter and solve the problem?

Thanks,

Yifang

It shows the following:

> if (!requireNamespace("BiocManager", quietly = TRUE))

+     install.packages("BiocManager")

> BiocManager::install("S4Vectors", version = "3.8")
