I'm very new to R and I live in Mali, west Africa. I'm on *OS X 10.7.5*. I downloaded and installed *R 3.2.1*. I downloaded and installed *RStudio 00.99.893*. I ran through the free Microsoft data camp intro to R course, then started another free course through 'edX', for Data and Statistics for Life Sciences, using R. The first prompt in the course is to install.packages("swirl"). Copied below are the various error messages I get when trying to install or load any package. My best guess is that the problems I'm having are due to being in west Africa, with unreliable connections, weak connections and no CRAN Mirror closer than Italy or Spain (as far as I know). I checked into common package errors on the RStudio page, but I'm not confident enough in my computing to get into internet proxies and some of the other suggested troubleshooting. Any insight would be very helpful. See error messages below. Thanks -- Tim - When attempting to install, the print-out I get in the Console in RStudio is any length of: > install.packages("swirl") % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 0 0 0 0 0 0 0 --:--:-- 0:00:10 --:--:-- 0 0 0 0 0 0 0 0 0 --:--:-- 0:00:10 --:--:-- 0 0 0 0 0 0 0 0 0 --:--:-- 0:00:11 --:--:-- 0 22 207k 22 48384 0 0 3833 0 0:00:55 0:00:12 0:00:43 19740 30 207k 30 64823 0 0 4808 0 0:00:44 0:00:13 0:00:31 19578 38 207k 38 81207 0 0 5638 0 0:00:37 0:00:14 0:00:23 19193 46 207k 46 97591 0 0 6299 0 0:00:33 0:00:15 0:00:18 20076 53 207k 53 111k 0 0 6966 0 0:00:30 0:00:16 0:00:14 22717 69 207k 69 143k 0 0 8423 0 0:00:25 0:00:17 0:00:08 20487 76 207k 76 159k 0 0 8821 0 0:00:24 0:00:18 0:00:06 19621 92 207k 92 191k 0 0 10085 0 0:00:21 0:00:19 0:00:02 22841100 207k 100 207k 0 0 10363 0 0:00:20 0:00:20 --:--:-- 230100 207k 100 207k 0 0 10363 0 0:00:20 0:00:20 --:--:-- 23922 The downloaded binary packages are in /var/folders/yb/7z339kn56mdbwx92ydmsqswc0000gn/T//RtmpBzQ16u/downloaded_packages For other packages, ggplot2, forexample, a similar printout can run for hundreds and hundred of lines. So RStudio tells me that the packages are available to load, BUT: - when *loading* any package an error comes up saying package 'name of package' was built under R version 3.2.5 but info on swirl says it should work on any version of R above 3.0.2. I get similar errors for other packages (treemap, ggplot2, etc). - Or sometimes I"ll get this: Error : .onAttach failed in attachNamespace() for 'swirl', details: call: stri_c(..., sep = sep, collapse = collapse, ignore_null = TRUE) error: object 'C_stri_join' not found In addition: Warning message: package ‘swirl’ was built under R version 3.2.5 Error: package or namespace load failed for ‘swirl’ Any suggestions?
