数据索引的创建有三种方式:data步骤、sql步骤、datasets步骤。其中还是有点困惑在data与datasets的区别之上,datasets是对逻辑库中数据集进行操作的方式,而data之后是代表程序的开始。 1、data方式创建索引 代码语言:javascript 代码运行次数:0 运行 AI代码解释

You cannot explicitly tell the SAS System to use an index that has been created in processing. The SAS System will determine the most efficient way to process a query or statement. /* MERGE TWO SMALL DATASETS USING AN INDEX */ DATA GAPINFO1 (INDEX=(CLTNUM)); SET TEMP.GAPINFO; RUN; ...

x1 = c(5, 1, 4, 9, 1, 2, NA, NA, NA, NA, NA, NA) instead I get an error: Error: Can't combine `x1` and `x1` . Where/how in your series of pipe operators could I use the function as.numeric() on x1 variable – for all datasets in the list? or na.strings = c(...
To exactly determine the reason for your initial problem, we would need to see the variable list from proc contents for both datasets, or the log of your code execution, as the NOTEs would reveal the implicit type conversion(s) in your data steps. Maxims of Maximally Eff...

The word pseudo-image refers to the fact that any pseudo-image sample can be associated to a region in S (via a function of coarse co-registration). Then, denoting by K the set of indexes of the datasets, we distinguish within K, the sets of true image indexes, K′ with K′⊊K,...
