我目前正在尝试使用 RInside
在回测中做一些绘图,灵感来自 Saving Lattice Plots with RInside and Rcpp .我在编译 RInside
时遇到了问题。在深入探讨我的问题之前,我已经查阅了前三个问题:
但它无法解决我的问题。按照标准步骤,我安装了最新的 RInside
包,并执行了包含在下载的 RInside
二进制文件中的以下 makefile Makefile.win
:
## -*- mode: makefile; tab-width: 8; -*-
##
## Simple Makefile for Windows
##
## Note that the libRInside library encodes the value of R_HOME found
## at compilation. So if you use the CRAN package of RInside, its value
## may not correspond to where you have R installed. One quick fix is
## export the appropriate value of R_HOME, eg ony my work machine
## set R_HOME=C:\opt\R-current
## The other is to re-install RInside from source on your machine.
## Either one should allow you to actually run the binaries created
## with this Makefile
## This version is fairly directly derived from the Unix versions
## You may have to set R_HOME manually if this does not work
## It requires Rtools in the path -- as does all R package building
#R_HOME := $(shell R RHOME | sed -e "s|\\\\|\/|g")
R_HOME := "C:/R/R-3.1.3"
## You may have to set this to one of the two values below to enforce a particular
## architecture in case the autodetection in the next line does not work correctly
##R_ARCH := --arch $(shell echo 'cat(.Platform$$r_arch)' | R --vanilla --slave)
##R_ARCH := --arch i386
R_ARCH := --arch x64
## You may need to set R_LIBS_USER if Rcpp or RInside are installed where R does not see them by default
R_LIBS_USER := "C:/R/R-3.1.3/library"
sources := $(wildcard *.cpp)
programs := $(sources:.cpp=)
## include headers and libraries for R
RCPPFLAGS := $(shell $(R_HOME)/bin/R $(R_ARCH) CMD config --cppflags)
RLDFLAGS := $(shell $(R_HOME)/bin/R $(R_ARCH) CMD config --ldflags)
RBLAS := $(shell $(R_HOME)/bin/R $(R_ARCH) CMD config BLAS_LIBS)
RLAPACK := $(shell $(R_HOME)/bin/R $(R_ARCH) CMD config LAPACK_LIBS)
## include headers and libraries for Rcpp interface classes
RCPPINCL := $(shell echo 'Rcpp:::CxxFlags()' | $(R_HOME)/bin/R $(R_ARCH) --vanilla --slave)
RCPPLIBS := $(shell echo 'Rcpp:::LdFlags()' | $(R_HOME)/bin/R $(R_ARCH) --vanilla --slave)
## include headers and libraries for RInside embedding classes
RINSIDEINCL := $(shell echo 'RInside:::CxxFlags()' | $(R_HOME)/bin/R $(R_ARCH) --vanilla --slave)
RINSIDELIBS := $(shell echo 'RInside:::LdFlags()' | $(R_HOME)/bin/R $(R_ARCH) --vanilla --slave)
## compiler etc settings used in default make rules
CXX := $(shell $(R_HOME)/bin/R $(R_ARCH) CMD config CXX)
CPPFLAGS := -Wall $(shell $(R_HOME)/bin/R $(R_ARCH) CMD config CPPFLAGS)
CXXFLAGS := $(RCPPFLAGS) $(RCPPINCL) $(RINSIDEINCL) $(shell $(R_HOME)/bin/R $(R_ARCH) CMD config CXXFLAGS)
LDFLAGS = -s
LDLIBS := $(RLDFLAGS) $(RBLAS) $(RLAPACK) $(RINSIDELIBS) $(RCPPLIBS)
CC := $(shell $(R_HOME)/bin/R $(R_ARCH) CMD config CXX)
all : $(programs)
clean:
rm -vf $(programs)
checkR:
echo "R is at $(R_HOME)"
我在 Makefile.win 中所做的更改使其可执行 R_HOME := "C:/R/R-3.1.3"
, R_LIBS_USER := "C:/R/R-3.1.3/library"
,R_ARCH := --arch x64
,然后按照Problem with compiling RInside examples under Windows我的想法是将 RProfile.site
更改为:
# Things you might want to change
# options(papersize="a4")
# options(editor="notepad")
# options(pager="internal")
# set the default help type
# options(help_type="text")
options(help_type="html")
# set a site library
.Library.site <- file.path("C:/R/R-3.1.3/library")
# set a CRAN mirror
# local({r <- getOption("repos")
# r["CRAN"] <- "http://my.local.cran"
# options(repos=r)})
# Give a fortune cookie, but only to interactive sessions
# (This would need the fortunes package to be installed.)
# if (interactive())
# fortunes::fortune()
运行 make -f Marfile.win
,我将 cmd 复制为:
