1. 确认eval(predvars, data, env)函数的调用上下文 eval函数在R语言中用于评估表达式。其常用形式为eval(expr, envir = .GlobalEnv, enclos = if (is.list(envir) || is.pairlist(envir)) parent.frame() else baseenv()),但在你的情况下,使用了三个参数:predvars、data和env。这里,predvars可能是包含变量...
Calculate log10(nCount) and put into the query metadata query@meta.data['log_umi'] <- log10(calcn$nCount) StefanMDPhD commented Jan 30, 2024 @hoangan-nguyen. Thanks that really helped. Specifically what worked for me was: query@meta.data['log_umi'] <- log10(query$nCount_RNA)Sig...
As you see, I pass a vector 'x ' to my function, which I would have expected to be passed to the functionlm(x ~ 1), but instead I get the messageError in eval(predvars, data, env) : object 'x' not found. The same code without the wrapper function works fine. W...
1. 随机森林 我在用R语言做文本分析后的数据的预测的时候发现,在进行随机森林建模时报错:Error in eval(predvars, data, env) : 找不到对象’000’。 经过分析,这是因为使用了不合法的变量名的原因。随机森林对这点比较敏感。像决策树和朴素贝叶斯可能不会报错。 解决方法 像我这个,就是用了000作为变量名,这...
Error in eval(predvars, data, env): object 'FEATURE_NAME' not found Here FEATURE_NAME is a onehot encoded column name. ex - if categorical column name is "columnA" , "value1" is the value. Then the FEATURE_NAME is "coulmnAvalue1" my prob...

> predict(M,newdata=df$x,interval=”confidence”) Error in eval(predvars, data, env) : numeric ‘envir’ arg not of length one In this example, we enter a data frame column into the “newdata” argument of the predict function. The problem occurs because the column is a vector and...
