然后想用同样的数据再用ggplot2画张图。用p <- ggplot(data=filename, mapping = aes(x=V1))时总显示⚠️Error:’data’ must be a data frame, or other object coercible by ‘fortify()’, not a numeric vector. 补充信息:用head(filename)出来的是一个有两列的matrix赞...
针对您提出的问题“argument x must be a data frame or list of data frames”,这里我将按照您给出的提示,分点进行回答,并包含必要的代码片段来佐证。 1. 确认x的当前数据类型 在R语言中,您可以使用class()函数来检查x的当前数据类型。例如: R class(x) 这将返回x的数据类型,如"numeric", "character"...
when working with data in R, it is important to remember that input data must be numeric. In this article, we will explain why this is the case and provide some examples to illustrate this concept.
However, the height argument of the barplot function only takes numeric vectors or matrices as input. So how can we solve this problem? That’s what I’ll show next! Example 2: Fix the Error in barplot.default() : ‘height’ must be a vector or a matrix ...
When using the bar plot function, It will accept either a numerical vector or matrice for the height of the bars. Consequently, if you try to use a data frame or a non-numeric vector you will get the “’height’ must be a vector or a matrix” error message. The easiestway to ...
x: numeric vector, data matrix or data frame FUNcluster: a clustering function including “kmeans”, “pam”, “clara”, “fanny”, “hclust”, “agnes” and “diana”. Abbreviation is allowed. hc_metric: character string specifying the metric to be used for calculatin...

In Example 1, I’ll show how to replicate the error message “Aesthetics must be either length 1 or the same as the data” in R. Have a look at the following R code: ggplot(data, aes(x, y, fill=c("red","blue")))+# Try to draw ggplot2 plotgeom_bar(stat="identity")# Error...
"Simple" SQL to check for alpha or numeric charcters isn't working right "String or binary data would be truncated.\r\nThe statement has been terminated." "String or binary data would be truncated" and field specifications “Unable to enlist in the transaction” with Oracle linked server fro...
This is done to figure out towards what cells in the neighborhood of a cell i should the velocity D_i be projected. I am not sure what’s causing the issue here ... perhaps you have some duplicated cells. Is it just the diagonal values of the return matrix that are NaN? Can you ...
