linux - calling R from within Matlab -


i trying run r script within matlab, , same error poster: calling r matlab

as far can tell situations same, except system running linuxmint (release 14 nadia, kernel 3.5.0-17-generic) , solution in post not work me. make further suggestion? i'm stumped.

like poster in above thread, call works shell not within matlab.

r_script.r contains:

foo <- rnorm( 100 ) cat( sd( foo ), '\n' ) cat( mean( foo ), '\n' )

the error message within matlab:

>> system( 'rscript /tmp/r_script.r' ) error in dyn.load(file, dllpath = dllpath, ...) :    unable load shared object '/usr/lib/r/library/stats/libs/stats.so':   /usr/local/matlab/r2013a/sys/os/glnxa64/libgfortran.so.3: version `gfortran_1.4' not found (required /usr/lib/liblapack.so.3) during startup - warning message: package ‘stats’ in options("defaultpackages") not found  error: not find function "rnorm" execution halted  ans =       1  >> !unset dyld_library_path;  >> system( 'rscript /tmp/r_script.r' ) error in dyn.load(file, dllpath = dllpath, ...) :    unable load shared object '/usr/lib/r/library/stats/libs/stats.so':   /usr/local/matlab/r2013a/sys/os/glnxa64/libgfortran.so.3: version `gfortran_1.4' not found (required /usr/lib/liblapack.so.3) during startup - warning message: package ‘stats’ in options("defaultpackages") not found  error: not find function "rnorm" execution halted  ans =       1

ok, responses amro , dwin got me pointed in right direction , i've solved problem. problem matlab seems include own version of libgfortran.so.3, must out of date compared version on system (and expected r). many amro , dwin helping me out.

for poor soul comes along later:

i able determine running ldd on /usr/lib/r/library/stats/libs/stats.so both inside , outside of matlab.

!ldd /usr/lib/r/library/stats/libs/stats.so (from inside matlab) returns:

<snip> libgfortran.so.3 => /usr/local/matlab/r2013a/sys/os/glnxa64/libgfortran.so.3 (0x00007faff0bbc000) </snip>

and ldd /usr/lib/r/library/stats/libs/stats.so (from shell) returns:

<snip> libgfortran.so.3 => /usr/lib/x86_64-linux-gnu/libgfortran.so.3 (0x00007f3c9b308000) </snip>

adding system libgfortran.so.3 beginning of matlab's ld_library_path (not end) solved problem. within matlab:

>> setenv( 'ld_library_path', strcat( '/usr/lib/x86_64-linux-gnu:', getenv( 'ld_library_path' ) ) ) >> !/usr/bin/rscript /tmp/r_script.r                                                                0.8317391  0.09262757

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
