You need to issue all commands in one system()
call:
system(paste("cd",getwd() "&& bgame -y 2010 2010bos.eva >2010bos.txt",sep=" "))
You should already be in your working directory, so I’m not sure the cd getwd()
is necessary. And you may need quotes around your path because it contains spaces. The error may be resolved by putting spaces around >
.
If I were in your shoes, I would try this:
system("bgame -y 2010 2010bos.eva > 2010bos.txt")
UPDATE:
And you should probably heed this advice in the “Differences between Unix and Windows” section of ?system
that says you should use shell
:
• The most important difference is that on a Unix-alike
‘system’ launches a shell which then runs ‘command’. On
Windows the command is run directly - use ‘shell’ for an
interface which runs ‘command’ _via_ a shell (by default the
Windows shell ‘cmd.exe’, which has many differences from the
POSIX shell).
This means that it cannot be assumed that redirection or
piping will work in ‘system’ (redirection sometimes does, but
we have seen cases where it stopped working after a Windows
security patch), and ‘system2’ (or ‘shell’) must be used on
Windows.
