R - get all variables created from function call -

-

It's crazy, and only with intellectual curiosity: can I run a function in R such that after the function Can I get all the variables created when the function is executed? So the ability to see a function before coming back? I do not mean to enter the function in debug mode.

I'm not sure what it is you want, but maybe close to you Trace can embed an intermediary expression: 

  & gt; Trace (Lm, exit = function). Last_env & lt; & Lt; - "LM" tracing function "statistics" in parent.frame ()) package [1] "LM" & gt; LM (y ~ x, data.frame (x = 1: 10, y = 10: 1)) LM on exit call (y ~ x, data.frame (x = 1:10, y = 10: 1)) Tracing: LM (formula = y ~ x, data = data. Frames (x = 1:10, y = 10: 1)) Coefficient: (interception) x 11 -1 & gt; LS (.last_env) [1] "cl" "contradiction" "data" "formula" "m" method "mf" model "" mt "" na.action "" offset "[12]" qr "ret.x" "Ret.y" "singular.ok" "subset" or "weight" "x" "y" "z" & gt; ("Cl", .last_env) LM (formula = y ~ x, data = data.frame (x = 1:10, y = 10: 1))    < / Html>

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
