get_ram not working on Windows 10

When I run get_ram it returns NA B.

Here is my sessionInfo()

Could you run

system("wmic MemoryChip get Capacity", intern=TRUE)

and tell me what that returns?

[xiaodaigh]

"Capacity \r" "17179869184 \r" "17179869184 \r" "17179869184 \r" "17179869184 \r" "\r"

Thanks. Do you 16Gb of RAM or 4 * 16GB?

[xiaodaigh]

4 * 16G

I also get NA B and system("wmic MemoryChip get Capacity", intern=TRUE) returns [1] "Capacity \r" "4294967296 \r" "4294967296 \r" "\r". My machine has 8GB, so 2x4GB chips.

[xiaodaigh]

this works for me

system('grep MemTotal /proc/meminfo', intern = TRUE)
l = strsplit(a, " ")[[1]]
l = as.numeric(l[length(l)-1])
ram_size = l/1024^2

In fact, I have used this in the disk.frame package.

@xiaodaigh Does that work under windows 7 and 10?

[xiaodaigh]

Windows 10 but haven't tested on Windows 7.

[csgillespie]

Thanks everyone. I've added the method proposed by @xiaodaigh and used the previous method as a fallback.

I am also having the same problem where Get_ram() produces “NA B”

I used your code:

system("wmic MemoryChip get Capacity", intern=TRUE)

With an output of:

"Capacity \r" "17179869184 \r" "17179869184 \r" “\r”

This checks out since I have two 16 gb chips.

I run into the same problem under windows 10 with package version 1.0.7

[gxc251]

Same here under Windows 10, package version 1.0.7, and R version 4.1.0
system("wmic MemoryChip get Capacity", intern=TRUE)
[1] "Capacity \r" "17179869184 \r" "17179869184 \r" "\r"
get_ram()
NA B
