如何从列表中绘制R中具有背景(splsda模型)的单个观测值的多个图?
我在R中对10个数据帧(10个研究区域的数据)执行splsda模型,存储为列表(如何从列表中绘制R中具有背景(splsda模型)的单个观测值的多个图?,r,list,plot,lapply,R,List,Plot,Lapply,我在R中对10个数据帧(10个研究区域的数据)执行splsda模型,存储为列表(datalist)。所有这些数据帧都是相似的,具有相同的变量,但只是不同的值 > head(datalist[[1]]) OID POINTID WETLAND TPI200 TPI350 TPI500 TPI700 TPI900 TPI1000 TPI2000 TPI3000 TPI4000 TPI5000 TPI2500 1 -1 1 no wetl 70 67 5

dput(datalist[[1]])
可以找到(wetransfer中的txt文件)
我已经使用lappy
使用两个组件执行了splsda.model
,这将导致model\u列表
:
library(mixOmics)
custom_splsda <- function(datalist, ncomp, keepX, ..., Xcols, Ycol){
Y <- datalist[[Ycol]]
X <- datalist[Xcols]
res <- splsda(X, Y, ncomp = ncomp, keepX = keepX, ...)
res
}
model_list <- lapply(datalist, custom_splsda, ncomp = 2, keepX = c(5, 5), Xcols = 4:8, Ycol = "WETLAND")
库(混合组学)
custom_splsda根据您提供的示例数据,这里提供了一个解决方案,用于将每个绘图保存在一个pdf中。为了使练习具有可复制性,我使用您添加的输入创建了datalist
。在您真正的问题中,您必须具有带有名称的datalist
,以便将标题添加到绘图中。另外,一些绘图数据不可用,如datastudyarea1
,但为您完成这部分代码并不困难。这是草图:

#资料
数据列表请dput(数据列表)
或dput(数据列表[[1]])
使您的问题重现并帮助您@鸭子,数据列表太大了!所有数据帧都包含超过10000-20000行!我无法进行dput(型号列表[[1]])
!但是我编辑了这篇文章,并发布了数据列表的第一个研究区域(第一个元素/数据框架)
!这有帮助吗?@还有你添加的数据,我能够回答你昨天发布的问题!您可以检查一下,看看这是否适合您:)
