r - Dataframe shape when using directlabels + ggplot -


मेरे पास निम्न डेटाफ़्रेम है 

  # डेटा वर्ष & lt; - c (1500,1750 , 2000) देश 1 & amp; lt; - c (10,20,30) देश 2 & lt; - c (30,50,40) df & lt; - data.frame (वर्ष, देश 1, देश 2)
< P> जो मुझे 

  # प्लॉट की आवश्यकता है (ggplot2) myplot & lt; - ggplot (डीएफ, एईएस (वर्ष)) के साथ साजिश है + geom_line (aes (y = country1)) + geom_line (एईएस Y = देश 2)) + प्रयोगशालाओं (y = "गायों")

सभी अच्छे तब मैं लाइन 'लेबल जोड़ना चाहता हूँ और मैं कोशिश करता हूं 

  # लेबल जोड़ें (directlabels) direct.label (myplot)

जो फेंकता है 

  त्रुटि Direct.label.ggplot (myplot) में: डिफ़ॉल्ट सीधी लेबल अनुमान लगाने के लिए रंगीन सौंदर्य की आवश्यकता है।

मुझे लगता है कि समस्या यह है कि मेरा डेटाफ़्रेम ggplot के लिए अच्छा नहीं है क्योंकि मेरी लेबल कॉलम के नाम हैं।

क्या मुझे अपने डेटा ढांचा? reshape2

फिर से नवाचार करने का सबसे आसान तरीका (मेरी राय में) / कोड> पैकेज 

  df & lt; -data.frame (वर्ष = सी (1500, 1750, 2000), देश 1 = सी (10, 20, 30), देश 2 = सी (30, 50 , 40)) जीपीएस (एमआईएम, एईएस (वर्ष, मान, रंग = चर)) + जीओएम_लाइन ()) # आरएपीपी लाइब्रेरी (रीशेप 2) मिमी & lt; -melt (df, id.var = "वर्ष") # प्लॉट मायप्लोट 2 & amp; + लैब्स (y = "गायों") # लेबल लेबल लाइब्रेरी (डायरेक्टलाबेल) direct.label (myplot2)

इस तरह हम उचित" रंग "सौंदर्य प्रदान कर सकते हैं कि direct.labels फ़ंक्शन की तलाश है।

Python Equivalent for matlab cart2pol and pol2cart -

I would like to use pol2cart and cart2pol for two functions in MATLAB. Is there an equivalent Python Function? Or if we can define work? For example, I tried to use the CeMatePactor function, but it only accepts one argument, I have 2 arguments to cross the polar and REC function. P> I have tried to use this function for cart2pol: def cart2pol (x, y): theta = atan2 (y, x) rho = Sqrt (x ** 2 + y ** 2) returns (theta, ro) thanks

Docker - Tomcat and PostgreSQL containers in same host - No Route to host -

I have a web application running on Tomcat and has started the container using the command, Docker run -d -p 8080: 8080 tveuser / tve-repository: tve-services I also run a PostgreSQL container on the same host using the following command am: Docker run-D-P 80: 80-P-5432: 5432 Tivejhr / Tive-repository: TV-post-Jiaracl I Verify that PostgreSQL is running using phpPgAdmin but Neither could it find the tomato to connect. 'Docker PS' also tells me that both the containers are up and running. I connect the web entry to the database through the TOKamet Reference.XML which contains the entry & lt; Parameter Name = "abc.connection.url" value = "jdbc: postgresql: //1.2.3.4: 5432 / dbname" /> Where 1.2.3.4 is the Dockers Host IP in which the Container is Running. But when I run the Tomcat Container, I get the following error: Org.postgresql.util.PSQLException: The connection attempt failed. On Org.postgresql.core.v3.ConnectionFactoryI...
