Mixedorder data frame in R

前提是你 提交于 2019-12-20 06:05:02
问题 I have a data frame which looks like this : a = c("1A","10A","11A","2B","2C","22C","3A","3B") b= c(1,2,3,4,5,6,7,8) ab = data.frame(a,b) and I want to sort it according to the column a . I tried the mixed order library(gtools) ab[mixedorder(ab$a),] but I don' t get the result I want (1A,2B,2C,3A,3B..). How can I fix this? 回答1: We need to convert to character class (as the 'a' column is factor based on the default option in data.frame call i.e. stringsAsFactors=TRUE ) ab[mixedorder(as

问题 I got the following XSD bit from a customer. It is part of a legacy schema that spans over dozens of files. <xs:element name="stateProvinceName"> <xs:complexType mixed="true"> <xs:attributeGroup ref="xml:attlist.global-attributes"/> </xs:complexType> </xs:element> I'm trying to figure out what they actually want. There are no sub-elements, so what is the meaning of this 'xs:mixed'? is it supposed to be simpleContent, or no content? I told them that they should use more standard construct, e.g

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 2 years ago . My requirements: The data structure must be able to hold an arbitrary number of elements (on the order of hundreds of thousands). The data structure must use memory efficiently. In this case, that means adding on an extra hundred thousand items whenever they are needed. The data

问题 I am trying to get a windows service to work but I keep getting the following error... Mixed mode assembly is built against version 'v1.1.4322' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information. The windows service is pretty simple. It looks at some data, does some organization and sends some information of to a database. If the data meets certain conditions, the service connects to K2 Workflow, find the correct item, then claims and completes

Ignore non-number values in a list and find the sum recursive method

丶灬走出姿态 提交于 2019-12-12 02:55:18
问题 I need to create a recursive method in LISP that takes the numbers in a list and finds the sum. Anything in the list that is not a number is skipped (For example, if the list contains "Cheese 12 Dog 8 Shoe 5", the output would be 25). Right now my code finds the sum, but throws an error if there is anything in the list that is not a number. What can be changed to fix that? (defun adder (lis) (cond ((null lis) 0) (t (eval (cons '+ lis)) ) ) ) 回答1: This would do: (defun adder (lis) (if (null

Questions about converting a mixed-encoding file to UTF8 in Perl

问题 I'm in the process of converting files generated by the ancient DOS-based library program of our university's Chinese Studies Department into something more useful and accesible. Among the problems I'm dealing with is that the exported text files (about 80MB in size) are in mixed encoding. I'm on Windows. German umlauts and other higher-ASCII characters are encoded in cp1252, I think and CJK-characters in GB18030. Due to "overlapping" encodings, I can't just drag the whole file into Word or

Pandas: Coloumn with mixed datatype; how to find the exceptions

好久不见. 提交于 2019-12-08 05:49:02
问题 I have a large dataframe, and when reading it, it gives me this message: DtypeWarning: Columns (0,8) have mixed types. Specify dtype upon import or set low_memory=False. It is supposed to be a column of floats, but I suspect a few strings snuck in there. I would like to identify them, and possibly remove them. I tried df.apply(lambda row: isinstance(row.AnnoyingColumn, (int, float)), 1) But that gave me an out of memory error. I assume there must be a better way. 回答1: This will give you True

dtd and mixed content

旧时模样 提交于 2019-12-08 04:52:53
问题 Does someone know way a mixet content element (in dtd) there is a need to add the "*" at the end? For example: <!ELEMENT note (#PCDATA|to|from|header|message)*> I'm reffering to the case where I don't want to repeat anything again... I just want to be able to choose between #PCDATA and other elements. I know that if I drop the "*" in the end of the decleration I will get a bad DTD decleration... But - I have no idea what is the reason of that... Anyone know why? 回答1: You're hitting this
