我试图将一个hdf5加载到R并遇到一些问题.以下是我配置环境的步骤:
我怀疑我遇到的问题与我的HDF5版本和R模块期望的版本中的不兼容性有关.为了完整起见,我是如何安装R模块的:
R CMD INSTALL --configure-vars ='CPPFLAGS = -I/opt/local/include'--configure-args =' - with-hdf5 =/opt/local'hdf5_1.6.9.tar.gz
这很好.库似乎加载没有问题,但我尝试加载文件时没有返回数据:
库(HDF5)
hdf5load( "test.h5")
空值
然而,
osx:data scott $ h5dump test.h5 HDF5"test.h5"{GROUP"/"{DATASET"dset"{DATATYPE H5T_STD_I32LE DATASPACE SIMPLE {(31)/(31)} DATA {(0):1,2,4 ,8,16,32,64,128,256,512,1024,2048,4096,8192,(14):16384,32768,65536,131072,262144,524288,1048576,2097152,(22):4194304,8388608 ,16777216,33554432,67108864,134217728,(28):268435456,536870912,1073741824}}}}
有什么想法吗?
提前致谢.
使用verbosityin 参数hdfload()并使用 检查您的环境ls()。hdfload()有一个副作用,它将表加载到当前环境中,NULL是默认返回值。如果使用参数,load=TRUE对象将作为命名列表的组件返回:
load:逻辑值。如果为“FALSE”,则对象将作为命名列表的组件返回。如果为“TRUE”(默认值),则对象将作为具有自己名称的单独变量加载 - 在这种情况下,函数不返回任何内容。 在我的 Mac 上,使用相同的设置一切都运行良好。
