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.
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...
Empty and NA data lead to various errors. Closely related: #800 (comment) ComplexHeatmap::anno_barplot(c()) # 'data' must be of a vector type, was 'NULL' ComplexHeatmap::anno_barplot(c(NA)) # missing value where TRUE/FALSE needed Complex...
The previous R code leads to the error message “`data` must be a data frame, or other object coercible by `fortify()`, not an integer vector”. The reason for that is that we have tried to specify a numeric vector as data argument. ...
In addition, before you can deploy any synthetic voice model created using a custom neural voice lite project, the voice talent must provide an additional recording in which they acknowledge that the synthetic voice will ...
MATLAB table — Variables must be double-precision numeric vectors. Variable names are the names in the VariableNames field of the Properties property. Numeric vector or matrix — For a matrix, each column is a separate variable named variableNamej, where j is the corresponding column. Regardless...
A commonly used array of std_logic is to define a byte: “array(7 downto 0) of std_logic”. Of course the std_logic_vector type is a shorthand for this and is equivalent to “std_logic_vector(7 downto 0)”. Arrays can't be applied directly to a signal, they must first be ...
This manipulation is highlighted because as exemplified in Figure 3, the behavior of a CU with NTLs can change soon after the irregularity is identified and rectified. Therefore, the algorithm must be trained with data that clearly show the behavior of the CUs during the period of irregularity ...
filename plus _datatype (default) | character vector | string scalar Name of the generated function, specified as the comma-separated pair consisting of 'OutputFunctionName' and a character vector or string scalar. The 'OutputFunctionName' value must be a valid MATLAB function name. The default...
A related yet different problem that had been studied is how to reconstruct traffic states based on loop detector data. In such studies, trajectory data were usually used as ground truth for model calibration or validation. It must be noted that trajectory data-based traffic state reconstruction ...
