这应该很容易,但我发现的所有例子都有不同的目标.
我得到了这些清单:
lst1 = list(
Plot = TRUE,
Constrain = c(1:10),
Box = "plot"
)
lst2 = list(
Plot = FALSE,
Lib = "custom"
)

它存储应该覆盖默认值的默认参数(lst1)和自定义参数(lst2).我想要的结果是:
>lst
$Plot
[1] FALSE
$Constrain
[1] 1 2 3 4 5 6 7 8 9 10
$Box
[1] "plot"
$Lib
[1] "custom"

所以:
对不起,我无法弄清楚.我试过merge(),但是:
lst=merge(lst2,lst1)

给
[1] Plot Lib Constrain Box
<0 Zeilen> (oder row.names mit Länge 0)

- 编辑 - fabians建议的解决方案正是我所需要的.更多:它处理嵌套列表,例如
ParametersDefault = list(
Plot = list(
Surface = TRUE,
PlanView= TRUE
),
Constrain = c(1:10),
Box = "plot"
)
Parameters = list(
Plot = list(
Surface = FALSE,
Env = TRUE
),
Lib = "custom"
)
Parameters = modifyList(ParametersDefault,Parameters)
print(Parameters$Plot$Surface)
# [1] FALSE

非常感谢!
