可能的包与 minpack.lm 冲突以进行 nlsLM 优化
Possible Package conflicts with minpack.lm for nlsLM optimization
问题:tidyverse
、ggplot2
和dplyr
是否可以与minpack.lm
冲突
以某种方式导致 nlsLM
在下面给出此错误?
"Error in numericDeriv(form[[3L]], names(ind), env) :
Missing value or an infinity produced when evaluating the model"
如果我运行脚本没有加载tidyverse
、ggplot2
和dplyr
、nlsLM
运行s
美好的。但是,加载这些包后,它会失败。我需要 tidyverse
、ggplot2
和 dplyr
用于其他目的。我已经为此工作了将近三个星期,但没有任何进展。有人知道解决这个问题的方法吗?

这两个都是导致问题的两个屏蔽函数。但是,你一个电话还是电话tidyverse
。 (当您调用 tidyverse
时,ggplot2
和 dplyr
已被调用,因此无需再次调用它们。)要将这两个屏蔽函数改回原来的状态,请保持您的代码正常工作,同时使用 tidyverse
,将其添加到代码中:filter <- stats::filter
和 lag <- stats::lag
,它将起作用。但是,如果您想使用这些调用的 dplyr
版本,您可以将它们改回或将库附加到函数。
library(tidyverse)
library(minpack.lm)
# change back the only two masked functions
filter <- stats::filter
lag <- stats::lag
从这里,调用您的数据对象 df1
和您最初调用的其他函数。
# objects & df used in ans.2 function:
h <- 552
mp <- 77
R_ <- 0.00831
K <- 273.15
gstart <- data.frame(h = c(550)) # mp=c(70,80), h=c(500,600), mp=c(77)
# exponential function for finding v in df1:
ans.2<- function(x){

-(1/ (1 + exp((h/ R_)*((1/ (lag(x) + K)) - (1/(mp + K))))))
/((x - lag(x)) + K))
}
ans.2(x = df1$t) # checking if function works
# finding values of h and mp, minimize residual sum of squares (RSS) between C and v:
# non-expanded ans.2
nlsLM(formula = C~ ans.2(x = df1$t),
data = df1,
start = list(h = 550,
mp = 77),
trace = T)
#nlsLM test:
nlsLM(formula = C ~ h*((
(1/ (1 + exp((h / R_)*((1/(t + K))-(1/(mp + K))))))
-(1/ (1 + exp((h / R_)*((1/(lag(t)+ K))-(1/(mp + K))))))
) /((t - lag(t)) + K)), data = df1, start = gstart, trace = T)
# saving nlsLM outputs
nls_1 <- summary(nlsLM(formula= C~ h * (
((1/(1 + exp((h/ R_)*((1/ (t + K))-(1/ (mp + K))))))
-(1/ (1 + exp((h/ R_) * ((1/ (lag(t) + K))-(1/ (mp + K))))))
/((t - lag(t)) + K))),
data = df1,
start = list(h = 50), #,mp=77
trace = F))
你会得到一个错误:
Error in nlsModel(formula, mf, start, wts) :

这是我找到的模型结果。
# Formula: C ~ h * (((1/(1 + exp((h/R_) * ((1/(t + K)) - (1/(mp + K)))))) -

问题:tidyverse
、ggplot2
和dplyr
是否可以与minpack.lm
冲突
以某种方式导致 nlsLM
在下面给出此错误?
"Error in numericDeriv(form[[3L]], names(ind), env) :
Missing value or an infinity produced when evaluating the model"
如果我运行脚本没有加载tidyverse
、ggplot2
和dplyr
、nlsLM
运行s
美好的。但是,加载这些包后,它会失败。我需要 tidyverse
、ggplot2
和 dplyr
用于其他目的。我已经为此工作了将近三个星期,但没有任何进展。有人知道解决这个问题的方法吗?

这两个都是导致问题的两个屏蔽函数。但是,你一个电话还是电话tidyverse
。 (当您调用 tidyverse
时,ggplot2
和 dplyr
已被调用,因此无需再次调用它们。)要将这两个屏蔽函数改回原来的状态,请保持您的代码正常工作,同时使用 tidyverse
,将其添加到代码中:filter <- stats::filter
和 lag <- stats::lag
,它将起作用。但是,如果您想使用这些调用的 dplyr
版本,您可以将它们改回或将库附加到函数。
library(tidyverse)
library(minpack.lm)
# change back the only two masked functions
filter <- stats::filter
lag <- stats::lag
从这里,调用您的数据对象 df1
和您最初调用的其他函数。

你会得到一个错误:
