> m <- fit(m, Remainder) Error in fit(m, Remainder) : could not find function "fit"

这个错误可能是因为你没有正确加载 `prophet` 包或者版本不兼容。

在 `prophet` 包的早期版本中，使用 `fit()` 函数对时间序列模型进行拟合，但是在新的版本中，这个函数已经被替换为 `prophet()` 函数内部的一部分，因此不再需要手动调用。

如果你使用的是较旧的版本，可以尝试使用以下代码：

library(prophet)

# 创建时间序列模型
m <- prophet(my_data)

# 拟合数据
m <- fit(m, my_data)

如果你使用的是较新的版本，则直接使用以下代码即可：

library(prophet)

# 创建时间序列模型并拟合数据
m <- prophet(my_data)

如果你还是遇到问题，可以尝试重新安装 `prophet` 包或者升级到最新版本。

built-in function ‘remainder’ declared as non-function

As an AI language model, I cannot see the context in which you encountered this error, but I can provide a general explanation of what it means.

This error message typically indicates that the code is trying to use the built-in function ‘remainder’ as a function, but it has been declared as a non-function. This could happen if the variable or object that was declared as ‘remainder’ is not a function type, but rather a different type such as a number or string.

To fix this error, check the declaration of the ‘remainder’ variable or object and make sure it is of the correct type. Alternatively, you could rename the variable or object to something else that does not conflict with the built-in function name.

Could not parse the remainder: '('Y-m-d\TH:m:s')' from 'date('Y-m-d\TH:m:s')

It seems like you are trying to format a date string using the PHP function `date()`. The correct syntax for this function is `date(format, timestamp)`, where `format` is the desired date format and `timestamp` is the optional UNIX timestamp to be formatted.

For example, if you want to format the current date and time in the format "Y-m-d\TH:m:s", you can use the following code:

$dateString = date('Y-m-d\TH:i:s');

This will output a string like "2021-09-01T14:30:00". Note that you need to escape the special characters in the format string using a backslash, like in the example above where `\T` is used to represent the letter "T".
