is.atomic(vec) # Apply is.atomic function to vector # TRUEThe RStudio console returns the logical value TRUE, i.e. our data object vec is an atomic vector.As you can see in the help documentation of the $-operator (i.e. ?”$”), the $-operator can only be applied to recursive ...
'x' must be atomic 既然是排序出了问题,我试着自己在 RStudio 里对目标数据框进行手动排序(点排序箭头),结果发现有一列报错了。 Error in (function (..., na.last = TRUE, decreasing = FALSE, method = c("auto", : unimplemented type 'list' in 'orderVector1' Error: VECTOR_ELT() can only ...
Strings: Character vectors are a more complex object made of vector CHARSXPs. Environments, or ENVSXPs. Functions, including CLOSXPs and the rarer BUILTINSXPs, SPECIALSXPs and FUNSXPs. Symbols, SYMSXPs. Pairlists, including LISTSXPs and the related NILSXP, LANGSXP, and DOTSXP. This chapter...

Suppressing the kinetically favorable lattice oxygen oxidation mechanism pathway and triggering the adsorbate evolution mechanism pathway at the expense of activity are the state-of-the-art strategies for Ru-based electrocatalysts toward acidic water oxi

For example, the one-class support vector machine utilizes a kernel function to circle the perfect unit cell inside a hyperplane, and the parts outside this circle are considered defects [12]. Another method trains the model using only defect-free images in an attempt to analyze the true ...
Fixes issue #251 by changing the order in which axis rotation rates are read from the angular velocity vector in the BNO055 IMU driver. Deprecates pitchMode in BNO055IMU.Parameters. Setting pitchMode to PitchMode.WINDOWS would break the coordinate conventions used by the driver. Moves OpMode...
These drawings were created way back when using an ancient vector-based illustration software application called MacDraw Pro. They look pretty awful and it’s certainly not the way I would render Michael today. In hindsight, I should have left them as line drawings and avoided the use of Mac...
