我正在通过R Studio完成我的分析，但我不断收到以下错误：
nls中的错误（Lambda~（exp（a +（b * AvgTemp）+（c *（AvgTempSQ））））*（（f +： 'data'中没有起始值的参数：Lambda，AvgTemp，AvgTempSQ，Avg9mpl2
我在我的数据上使用nls模型，这些模型是海龟种群。数据示例：

运行模型时，我不断收到上述错误。该模型如下：
nstart <- list(a=-119.95838,b=8.59843,c=-0.15402,f=0,g=0,h=0)
w <- list(999,999,999,999,999,999)
s <-list(-999,-999,-999,-999,-999,-999)
model <- nls(Lambda~(exp(a+(b*AvgTemp)+(c*(AvgTempSQ))))*
((f+(g*Avg9mpl2)+(h*(Avg9mpl2^2)))/(f+(g*Avg9mpl2)+
(h*(Avg9mpl2^2)))),
upper=w,lower=s,start=nstart,algorithm="port")
summary(model)
感谢您对上述方面的帮助。
