帮助解决:R错误:非数字参数数学函数从VAR模型
fcst.tmp < - 预测(VAR.tmp) 错误在轮(频率):非数字参数的数学函数
从代码:

colnames(tmp.matrix) <- c("Col1","Col2")
VAR.tmp <- VAR(tmp.matrix, p=1, type = "const")
fcst.tmp <- forecast(VAR.tmp)
PS
的tmp.matrix
需要被转换成虽然时间序列:
ts.matrix <- as.ts(tmp.matrix)
VAR.tmp <- VAR(ts.matrix, p=1, type = "const")
fcst.tmp <- forecast(VAR.tmp)
plot(fcst.tmp)
最后,你的错误是不可重现的。我尝试了'预测'功能来确保我获得了'VAR.tmp'的精美图。 – Masoud
