我再次遇到此错误。但与以前不同的是，现在下面的测试有效：
fx <- inline::cxxfunction( signature(x = "integer", y = "numeric" ) , '
return ScalarReal( INTEGER(x)[0] * REAL(y)[0] ) ;
' )
fx( 2L, 5 ) # returns 10 as should be
但是当我尝试任何基于 stan 的模型（例如下面的示例代码和数据）时，我得到与下面相同的错误。
以下是示例数据和代码：
DT<-structure(list(c = structure(c(1L, 1L, 1L, 1L, 1L, 1L, 2L, 2L,
2L, 2L, 2L, 2L, 2L, 2L), .Label = c("a", "b"), class = "factor"),
x = c(2004L, 2005L, 2006L, 2007L, 2008L, 2010L, 2012L, 2010L,
2012L, 2010L, 2005L, 2007L, 2012L, 2005L), y = c(11.05826397,
15.56776557, 49.50980392, 64.53900709, 75, 68.18181818, 99.86357435,
100, 99.26739927, 98.52941176, 100, 95.94594595, 99.64157706,
100)), class = "data.frame", row.names = c(NA, -14L))
library(brms)
fit <- brm(y~ x, data = DT)
它说“未创建函数/方法！”：
