java - Error installing R package -


edit:1 have seen using rjava package on win7 64 bit r

i have windows 7 64-bit machine r 3.1.0, java 7u67 64-bit installed. (note: not allowed update r)

java_home set c:\program files\java\jre7

and path includes

c:\program files\java\jre7\bin , c:\program files\java\jre7\server (the last entry jvm.dll file)

from r prompt can see rstudio using 64-bit r

r version 3.1.0 (2014-04-10) -- "spring dance" copyright (c) 2014 r foundation statistical computing platform: x86_64-w64-mingw32/x64 (64-bit)  > .machine$sizeof.pointer [1] 8

i can load rjava library fine 

> options(java.home="c:\\program files\\java\\jre7\\") > library(rjava)  warning message: package ‘rjava’ built under r version 3.1.1

but when try install install bigr package on machine , getting following error message

> install.packages("c:/local/bigr-1.0.tar.gz", repos = null, type = "source") installing package ‘c:/users/alex/documents/r/win-library/3.1’ (as ‘lib’ unspecified) * installing *source* package 'bigr' ... ** r ** inst ** preparing package lazy loading warning: package 'rjava' built under r version 3.1.1 error : .onload failed in loadnamespace() 'rjava', details:   call: indl(x, as.logical(local), as.logical(now), ...)   error: unable load shared object 'c:/program files/r/r-3.1.0/library/rjava/libs/x64/rjava.dll':   loadlibrary failure:  specified module not found.  error : package 'rjava' not loaded error: lazy loading failed package 'bigr' * removing 'c:/users/alex/documents/r/win-library/3.1/bigr' warning in install.packages :   running command '"c:/progra~1/r/r-31~1.0/bin/x64/r" cmd install -l "c:\users\alex\documents\r\win-library\3.1" "c:/local/bigr-1.0.tar.gz"' had status 1 warning in install.packages :   installation of package ‘c:/local/bigr-1.0.tar.gz’ had non-zero exit status

any solve problem appreciated..

i had same problem running library(rjava) on r 3.1.1 / rstudio 0.98.1073 on 64-bit windows 8.1 , 64-bit windows 7.

temporary solution set java_home environment variable in r/rstudio console @ start of each session:

in rstudio console on windows 7 64-bit latest java runtime installed:

sys.setenv(java_home='c:\\program files\\java\\jre7\\')

in rstudio console on windows 8.1 64-bit latest java sdk installed:

sys.setenv(java_home='c:\\program files\\java\\jdk1.8.0_20\\jre\\')

permanent solution requires adding new window's envionment variable appropriate java runtime folder:

add variable java_home equal c:\program files\java\jre7\

add variable java_home equal c:\program files\java\jdk1.8.0_20\jre\

i ran problem xlsx , xlconnect packages --- seem have missed notice these require java runtime installed , java_home environment variable set them work properly.

r newbie --- charles.

ps note when setting environment variable java_home in windows, path jre or jre7 not enclosed in single or double quotes , not require \ replaced \\ done when setting these in r/rstudio console window.

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
