原因：
pred$mean是Time-Series类型，rbind函数不支持。通过as.double将其转换成double类型即可。
修改前代码：
all_predata_time <- data.frame(pd=0.1,Row=1,preRow=0,pt=0.1,stasid='1',InitDate='1');
all_predata_time <- all_predata_time[-1,]
stasPowerPre_Time <- function(staid){
testSrc<-......
if(nrow(testSrc)>0)
{
maxDate <- max(testSrc$bizdate)
tsd<- ts(testSrc$dp,start=c(2016,01,01),frequency=365)
str(tsd)
x <- ets(tsd)
pred <- forecast(x,h=365)
predata <- data.frame(pd = pred$mean)
predata$Row <-as.integer(row.names(predata));
predata$preRow <- predata$Row -1;
predata$pt <- as.double(c(0));
predata$stasid <- staid;
predata$InitDate <- maxDate ;
all_predata_time <<- rbind(all_predata_time,predata)
}
}
修改后代码：
all_predata_time <- data.frame(pd=0.1,Row=1,preRow=0,pt=0.1,stasid='1',InitDate='1');
all_predata_time <- all_predata_time[-1,]
stasPowerPre_Time <- function(staid){
testSrc<-......
if(nrow(testSrc)>0)
{
maxDate <- max(testSrc$bizdate)
tsd<- ts(testSrc$dp,start=c(2016,01,01),frequency=365)
str(tsd)
x <- ets(tsd)
pred <- forecast(x,h=365)
predata <- data.frame(pd = as.double(pred$mean))
predata$Row <-as.integer(row.names(predata));
predata$preRow <- predata$Row -1;
predata$pt <- as.double(c(0));
predata$stasid <- staid;
predata$InitDate <- maxDate ;
all_predata_time <<- rbind(all_predata_time,predata)
}
}
